I'll check that.
thanks

loki666

almost there
I think we can address HeadPhones and Mic later

is that quirk file necesseary, since it's basically the same as the UCM BootSequence ?

can also be deleted

Is UI audio working for you at boot without hte quirk?

yup, but only for PPSSPP, it works fine in others for you ?

Yes it was working okay, but I wasn't sure if removing this quirk is what broke it for me since after boot I have to restart emulationstation before audio works on my dev branch and I had already removed quirk and the other patches. I'll have to bisect the changes to see what it was causing this.

no, that file has no effect for me

I do have UI sound in Duckstation if I launch it from the Tools menu, but launching a game crash

Probably the same for PPSSPP, I only test the UI, let me test a game

no it works in PPSSPP sa
EDIT: once

I think this related to the double prepare in dmesg I'll take a look at this later today

loki666 · 2026-03-24T21:03:11Z

made some tests...

I managed to get sound with PPSSPP sa, but that's about it...
PortMaster, RetroArch, Duckstation (didn't test them all) hang or crash

I can see alot of dmesg errors

I alsa had to add a wireplumber config to use software volume mixer, else volume doesnt work

monitor.alsa.rules = [
  {
    matches = [
      {
        device.name = "~alsa_card.*"
      }
    ]
    actions = {
      update-props = {
        # Do not use the hardware mixer for volume control. It
        # will only use software volume. The mixer is still used
        # to mute unused paths based on the selected port.
        api.alsa.soft-mixer = true
      }
    }
  }
]

loki666 · 2026-03-24T21:32:59Z

yikes ... it's worst I'd say ... now only scratch is getting out the speakers

sunshineinabox · 2026-03-25T19:50:54Z

I'll have to take a look on my device and actually try it again, it was working at one point something recent must have broken it. Also trying to chase down headphones issue in andriod I realized only th es8326 codec is on secondary, speakers are wired quarternary so I need to test some changes also. Didn't think patch would fix it, it was too easy and cosmetic.

loki666 · 2026-03-25T23:14:39Z

ok so with both pipewire patches from SM8650 for the buffer size, it works fine now
https://github.com/ROCKNIX/distribution/tree/next/projects/ROCKNIX/packages/audio/pipewire/patches/SM8650

should we merge this, and continue on headphones in a new branch ?

EDIT: I still have some clicks, but maybe we need to raise the buffer a bit more
and I still see the double start in dmesg

[   29.915341] aw88261 0-0034: start success
[   29.916202] aw88261 0-0035: start success
[   30.680627] ath10k_snoc c800000.wifi: chan info: invalid frequency 0 (idx 41 out of bounds)
[   36.225615] ath10k_snoc c800000.wifi: chan info: invalid frequency 0 (idx 41 out of bounds)
[   56.055314] aw88261 0-0034: start success
[   56.055918] aw88261 0-0035: start success

but not always it would seems, just rebooted, only one couple of start succes logs, and no clicks
so there is still something fishy

This reverts commit 24e98ca.
