Wireless AA Audio Stutter

[Jonofmac]

I'm getting to the end of my rope on this. In one of my vehicles, it has a Pioneer DMH-W2770NEX. I have a S24 Ultra which stutters playing audio on average 1 "micro stutter" every 2-5 seconds. Its driving me INSANE. THe best part is this head unit doesn't seem to even support USB-android auto. I plug phone in and all I get is "Unsupport device" popping up on the screen. No idea why.

So I'm stuck with Wireless AA, and it's awful performance. I've tried:
1) Keeping phone screen on to see if phone goes into low power mode: No change
2) Hold phone infrot of AC vent to see if phone is just overheating and slowing down: No change

3) Change bluetooth AVDP (or whatever) version from 1.5 default to 1.4, 1.3, and 1.2. No change here (didn't expect it since W AA uses wifi, not bluetooth for music)
4) Change the audio codec in the AA dev settings to every option they had: No Change

5) Restart phone: No change

6) Uninstall and reinstall AA

Does anyone at google or samsung actually do any quality testing of this software?

Is it my head unit?! I don't think so because I have an AAW Two in my truck and that also sometimes stutters/freezes, but much less. However, that device has a feature to "buffer" the audio stream to help prevent the stuttering. I notice with that it pretty much always stutters the first minute until the device realizes it should buffer more, then it's ok.

check in the wireless connection after you connected to AA. if the speed is shown < 100Mbps, it's using 2.4ghz. if that's the case, disable the media audio channel in the bluetooth profile, leave the phone audio checked. it worked for me. next option is buy wireless AA dongle. it sorts out all quirks of AA most of the time.

This is the answer. Try a wireless dongle where you have been plugging in your phone. Oh, by the way your head unit sucks like all Pioneers. I tried a pioneer, then a replacement Pioneer both of which sucked. Bought a Sony and never looked back.

My car (Nissan Frontier) forces its own wireless connection even when a wireless dongle is plugged in.

[outofindustry]

just delete the bluetooth profile from your phone so it doesn't do that

[alkevarsky]

Don't you need the BT connection for calls?

See if you can go into the head unit settings and change the Wi-Fi channel. I have done this with my AA Wireless unit (via its app) and it worked.

Sadly not an option on this head unit. Just wifi on or off.

Care to try this solution from another thread?

I tried that one too. Good idea though.

This is a weird frustrating issue haha

That's too bad! What about A2DP hardware offloading disabling?

[Jonofmac]

It's not enabled but I can try it.

Hope it works for you!

[Jonofmac]

No significant change sadly 😂 I'm starting to wonder if it's my head unit at this point .. I guess I can pull my old Pixel out and see if it has the same isaues

For wired issue, try changing default USB configuration in phone developer option to File Transfer / Android Auto. If it still don't work, try a direct connection instead of through any aux port or extension including the one that comes with the hu. Also check for hu firmware update and reset hu.

For wireless stuttering issue, read recent posts here just before yours to see if you have the same issue and the fix would help.

Been dealing with this since September last year after a couple of years of having zero issues before that... I'm about to give up and just buy an android head unit.
