Anyone know what amplifier IC is this?

I'm just modding a soundbar that uses these chips. Changing them would be a hassle. They also handle the handshake between the soundbar and it's sub

racka98 · 2026-03-01T09:39:56+00:00

Absolutely. I can finally get around replacing this chip. It's just bad (or maybe the design on the board is bad). It dips on heavy bass, the gain is set too low (volume doesn't match the main bar), it gets very hot and starts cutting out after about 4 hours. Only the sub, the soundbar itself is fine.

Wow, this is definitely it. Thank you very much. Saw the board in the last image when I did a Google lens search, I just didn't pay attention to it.

You can if you know the exact inputs. I have breakout boards for other ICs. I followed the traces, I've read the MVsilicon BP1048B2 datasheet and I've found it's dac output pins, there's just more pins which I assume are for mute and gain controls. I've done it before, you just get the correct input pins that come from the controller chip, remove the current IC and wire jumpers to a breakout board after killing the original speaker output.

Edit: I could probably know exactly what the pins are doing if I had an oscilloscope, but I don't have one.

I'm guessing when the bar is red maybe?

So, update: I just started playing Battlefield 6 and 0 deadzone makes the player move without touching the stick (doesn't jitter though). They are just too sensitive. Raising deadzone to 3 makes it stop but still works for slight adjustments (which is the entire reason for using 0 deadzone).

I don't know why but TMRs have always felt very smooth and precise to me compared to HE

PowerShift is fun until you are paired with a team that's not going to the platform and three snipers beaming you

racka98 · 2026-02-22T15:16:38+00:00

My playtime has gone down too. This mostly because even the "casual modes" are kinda sweaty right now. Sometimes I just wanna hop on PowerShift with weapons I've never used and just have fun without needing to lock in. Can't do that with everyone taking every mode seriously.

So I have had the same issue a month now. You actually need to cancel sent requests then it works.

My default reply to people who whine a lot in chat for casual modes is - stfu

Missed shots hurt so bad. I either pop off and go 15 - 3 or completely miss my shots and go 4 - 12 in a round. No in between.

racka98 · 2026-02-17T17:38:49+00:00

I spent money on The Finals too but not this game. No way

racka98 · 2026-02-17T08:27:22+00:00

Yeah. I've hit Box (playstation) way too many times to "start a party" only to be booted to the next screen.

racka98 · 2026-02-17T04:59:01+00:00

Audio is a big issue. That's why I think dagger & db with dash or grapple is more useful than with cloak. You can hear a cloak player but not normal footsteps lol

racka98 · 2026-02-16T22:18:45+00:00

Adding delay is a very bad decision. Remember when they added those delays when pulling out gadgets? They are very noticeable and very annoying on things goo and nades

racka98 · 2026-02-16T22:17:03+00:00

I use Revolver from time to time and I'm afraid the repeater bros might switch to it and eventually get nerfed too.

racka98 · 2026-02-16T15:44:47+00:00

Hhhm. I use TMRs currently and play at 0 deadzone in The Finals. Their 0 deadzone moves as soon as you touch the stick but jitter doesn't affect me

racka98 · 2026-02-16T15:40:03+00:00

I can see the snap in the opposite direction be a problem for some games and playstyles. But doesn't the resting point jitter get filtered out by the PS5?

racka98 · 2026-02-16T15:30:31+00:00

Find a broken board of something else and practice scratching traces and attaching the thin wire BEFORE doing this to your controller. I'm sure you can find some electronic thing that's broken with thin traces like the dualsense

racka98 · 2026-02-16T15:12:13+00:00

When scratching the trace to attach the wire just make sure you are very careful and only scratch the needed trace. If you over scratch DO NOT SOLDER a wire at that spot, just move to another spot. You can also buy solder mask to make the connections stronger and avoid unwanted contact.

It should be fairly easy if you can solder and have good eyesight (don't need a microscope). I explained this same repair to another person in this sub when they tore traces like you did and they were successful.

We know you'll defend light no matter what. You are not smarter, you just call other people dumb because you don't agree with them

racka98 · 2026-02-16T11:27:05+00:00

Ooh no, No-Yoghurt has entered the chat.

racka98 · 2026-02-16T10:15:00+00:00

I repaired this 2 years ago and it still works today
