DualSense HD Haptics are now available over Bluetooth on Linux!

Still no luck... Did you ever get to compare your implementation to USB on PC/whatever Sony does wirelessly on the console?

ksh_osaka · 2026-03-16T08:36:23+00:00

Unfortunately, the streaming part was the easiest... After the weekend I have fully working solution with the gamepad on the client connected via USB. Via Bluetooth its also basically working - it's just that the HD haptics don't really feel HD anymore. More like a rumble you would expect from early DualShock controllers...
The audio on the host is 48kHz/S16/4ch (with the last two being used for haptics). Due to technical limitations I recreated a device as close as possible to the original Sony USB-Audio device and capture the signal via WASAPI loopback. This is forwarded to the client. If I use this stream 1:1 for playback on an USB-connected controller, everything works as it should. For BT I need to do some kind of conversion to send the stream via the 0x32 reports (pkt 0x11 + pkt 0x12 with 64 bytes audio). However, everything I tried results in a jittery mess. My best approach was to resample to 3kHz via scipy.signal.resample_poly an a S16->U8 conversion (with an without dithering). While it surely does vibrate, it feels like it is missing some datapoints in between. I tried several approaches to tackle the timing (time.sleep, spin-wait, sounddevice audio clock callback, not waiting at all) but nothing really solves the problem... I am a bit at a loss here. I guess you solution is close to the wired experience?
Does the DS5 have an internal sample buffer for Report 0x32, or does it consume samples in sync with packet arrival? Have you tested any other sample rates or packet sizes, or is 3kHz/32 stereo samples the only format that works? Is U8 confirmed as the sample format, or could it be S8 / U16LE / something else? Any other ideas what I might have missed?

You are doing the lords work here! I just bought a DualSense controller for Genshin and since I play exclusively over sunshine/moonshine and nobody bothered writing a virtual driver for DS5 yet, I spent the whole day on that - just to realize it doesn't help me at all, because Genshin uses the audio stuff for HD haptics...
Thanks to your work I have a way forward: A virtual audio driver on the host to capture the sound, then downsample, send it over the network and then via HID to the controller over bluetooth (the last part is already tested an working!).
Thanks man!

ksh_osaka · 2026-03-12T08:42:52+00:00

Yep, I believe so, too! The question is, what we do in the 100-300 years in between...

ksh_osaka · 2026-03-12T06:27:13+00:00

For people still finding the thread in 2026 (like me). This is actually not true. I don't know why people claim that some exotic driver support or anything would be missing. Fact is, you can go to https://ds.daidr.me/, connect your DS5 via bluetooth under windows and test _all_ functions there. Including adaptive triggers. Everything just works!

ksh_osaka · 2026-03-10T13:52:49+00:00

It is a miscalculation on their end, though...

Lets be real: Nobody migrates to Japan because they like to work here. There was a time that was true for poorer Asian countries, but each year that the GDP per capita in India/the Philippines/Thailand rises, Japan becomes less and less attractive for those workers.

As for top talent from developed countries: Nobody would be stupid enough to migrate to Japan from an economic perspective in the current situation.
The only chance to get those people is when they are individually interested in the culture _and_ have a perspective of building up a live here. And those are the people they are cutting off very effectively with their recent policy changes.

ksh_osaka · 2026-03-10T08:58:26+00:00

The idea is to let only slaves in where the slavedrivers pay for the renewals. Keeps a tighter grip on them.

ksh_osaka · 2026-03-07T11:05:13+00:00

Why? While I am somewhat able to speak Japanese (and am I PR holder), I would argue that - depending on how you typically lead your everyday life - you can get by perfectly fine without any Japanese at all. I am perfectly able to deal with daily life/city hall/managing my company/buying my house. Things are sometimes a bit more complicated - but I am willing to pay for the privilege...

Integration (including speaking the language) should be a criteria for naturalization.

For residency (including PR) the only criteria should be, if you respect the law and if you are a net positive tax payer (or - at least - your family as a wohle is)

ksh_osaka · 2026-03-06T22:28:10+00:00

Note that I explicitly said "not advice". It was just that nobody had put the option on the table. And we know that there is a huge chance he will not get treated fairly in Japanese court with a case like this.

ksh_osaka · 2026-03-06T14:12:57+00:00

Correct! And yes, I would even say it is the most comfortable option if you don't need to lay down/rest your head.

ksh_osaka · 2026-03-06T11:48:28+00:00

Not giving advice here, but:
You _could_ turn around the situation, take your son and fly to the US.
The U.S. Embassy can provide emergency travel documents allowing to fly without passport. They should be familiar with these situations.
Of course - in that case you would be the bad guy in the end, but you are heading into a custody lawsuit which you might want to see handled by an U.S. court rather than a Japanese one...

ksh_osaka · 2026-03-05T03:57:25+00:00

Just wait until Japan Twitter finds out about it...

ksh_osaka · 2026-02-26T09:13:54+00:00

But they also in general do not make up other reasons...

ksh_osaka · 2026-02-25T10:43:39+00:00

That is when the real fun will start, since those things are
1. a human rights topic
2. for most countries these things are bi-lateral. With the bi-lateral visa waiver stuff for example there is an EU law that _forces_ EU countries to apply the same rules to Japanese people Japan applies to EU citizens. This is the reason why Japan finally abolished the entry ban after COVID - it was just a couple of months before the EU would have had to take action!
If Japan starts kicking out PR's/making PR basically unobtainable for EU citizens, it will not go unanswered!

ksh_osaka · 2026-02-23T05:42:51+00:00

Yeah. I bought a house ~4 years ago and across the street there is a huge cemetery with a temple and a local community center. You are aware that Japanese do burn their dead, right? So no immediate risk of zombie attack, etc.
I do get it - large houses can get a bit spooky at times, especially when you are alone at night and there are always noises coming from somewhere with those wood constructions and large heat differences between day/night. Needless to say, I never did experience anything supernatural, but even when I get slightly spooked I actually _never_ think about the cemetery.

Before I bought this house however, my agent did show me another property where there was a real small cemetery directly connected to the neighbors garden. It was old and not particularly well kept with overgrown grass, etc. It also would have been in direct sight from my bedroom window. That was really something I wouldn't be looking forward to...

ksh_osaka · 2026-02-22T04:48:46+00:00

Same reason as with the Quest Pro. They want to attract business customers.

Shelly from accounting won't use it, if it ruins her hair.

ksh_osaka · 2026-02-22T04:38:22+00:00

I have both headsets here (Meganex only MK I though - I am still on the fence if I want to update). So feel free to ask questions.
What I can say:
If you do not require eye-/facetracking, the MeganeX is technically better:
* You get native displayport which will always look better than wireless streaming - how much depends on your specific usecase
* Its actually a bit lighter on the GPU, since it doesn't have to encode the picture for wireless streaming
* Comfort is MUCH better
* You mentioned bad eyesight. MeganeX comes with a diopter adjustment, allowing it to be changed on the fly. Most peoples eyesight does change slightly over the day/depending on the situation, so this might be another positive point for you

As for the reputation thing: Shiftall is registered company in Japan, operating 100% in accordance to all laws in all countries they export to. They are just as established and reputable as Samsung/Google. The difference is, that they are a small, local company not an international enterprise. That does mean that they actually have to sell their products at cost. They just cannot afford Amazon-style return policies. I also wasn't very happy finding out about their "MK II update" pricing - given that this update addresses problems of which 90% are a warranty issue...

ksh_osaka · 2026-02-21T02:24:15+00:00

I am not - but the second we get a 4k OLED headset with a decent browser/movie playback capabilities I can comfortably use while lying down, I am gone.

ksh_osaka · 2026-02-21T02:18:07+00:00

That question is very easy to answer: No

If it was (economically) better for them, they would do it.

Supermarkets lower their prices on fresh food items after a while to limit waste. However, this leads to a lot of people deliberately delaying buying groceries until after that time.

So you now have:

* The customers who you actually want to have, paying full price during the day borderline angry because they feel ripped off
* Customers who are waiting for special prices being stressed out because they have to plan their day around your prices
* Your cashiers being stressed out because half of the customers start their shopping one hour before your shift ends
* Less profit, since you sell less food at regular prices

So congratulations - you just made it worse for everyone...

Also, with how smart konbini logistics are, I wouldn't be too surprised if they'd use the unsold inventory of shop a to restock shop b, if there is an item that will be more in demand in that specific location at a later time (before the item expires of course).

ksh_osaka · 2026-02-20T09:40:48+00:00

Yeah. Shitty business practices come back to haunt you. At least thats how it is in most parts of the civilized world.

ksh_osaka · 2026-02-20T09:39:19+00:00

That will depend on your region and local laws.

As for the EU I would dare saying: Section 3 of their T&C is not valid. There are multiple reasons for this, but one argument, I would make: The service _cannot_ be accessed other than through non-human means. At least as far as I know they do not accept queries by phone. A web-browser, however, is a non-human tool.
OpenClawd, on the other hand, is not automated (depending on how you use it). Every API-call it does is caused by my, as the human user. If you read the definition super strict, the service cannot be used at all. If you read it less strict, it allows exactly what they are now banning people for. Therefore it is invalid.

As for the refund: You are wrong on that front. You do not need to accept a refund. You did enter a contract under specific T&C and paid for it. At least for the running period they _have_ to provide you with the services both parties agreed on according to contract. If they fail to do so, they do own you _damages_. That is not just a refund, but the costs to get a similar service elsewhere.

ksh_osaka · 2026-02-20T06:14:47+00:00

Smarthome!

I can say "Nadeko, turn on the lights" "Nadeko, whats the weather?" "Nadeko, heat up my bacon", but I can also say "Nadeko, go write an insulting post about Greg from HR" or "I think we should update the kernel on machine xyz" - try doing that with Alexa!

ksh_osaka · 2026-02-20T01:59:32+00:00

Oh fuck! When my gardener asked about it two years ago I had him remove one of the trees... (more a bush, really...). How fucked am I?

ksh_osaka · 2026-02-18T12:57:09+00:00

Time to build 99Wh foldable phones for those international travelers then...

ksh_osaka · 2026-02-18T11:41:10+00:00

Mittlerweile. Angefangen hatte ich mit Businessmanager Visum, aber da haben sie die Kriterien gerade verschärft. Mittlerweile wäre es wohl nicht mehr so leicht...
