windows 1909 drivers update breaks ALC294 sound

[Alexey Kuznetsov]

Hello!

SHORT VERSION:

Recent windows drivers initialize ALC294 with 24bit 48000HZ, after rebooting to linux it produce garbaged sound (it decay every second, very strange effect). If you reboot from windows 10 1909 directly to linux it broken. You have to turn power off complete to reset the device.

LONG VERSION:

I recently install recent version of windows on separate partition and got garbaged sound on booth OS! My old version of windows was 1803 and everying was ok, I updated to 1909 and it got broken sound. Probably due to some firmware / configs / updates on sound chip. I let Windows to update drivers and notice my sound card driver got replaced by realtek drivers and sound got fixed on windows! But linux still not working propertly!

also-info.sh shows two devices:

This how it was on booth Linux and Windows 1810 before update. Windows also used to show two devices "AMD High Definition Audio Device", "High Definition Audio Device".
Something tells me alsa detect cards correctly. But now, something changed and alsa need to update configs...
Now Windows shows two devices: "AMD High Definition Audio Device" and second "Realtek(R) Audio".

As you can see from new windows drivers it detects two devices 1002:AA01 and 10ec:0294, but alsa keep detecting 1002:15de and 1022:15e3

On Ubuntu machine sound still completely garbaged and sounds like broken speakers. My headphones makes even stranger sounds. Not sure what to do.

I found several links about this issue here:

Windows 1909 without updates shows those id's:

AMD High Definition Audio Device/10.0.1.10/HDAUDIO\FUNC_01&VEN_1002&DEV_AA01&SUBSYS_00AA0100& REV_1007\5&14BACE15&0&0001

Windows 1803 without updates (old external installation, I still can boot here, and confirming those drivers produce exactly same sound issues like on linux):

AMD High Definition Audio Device/10.0.1.6/HDAUDIO\FUNC_01&VEN_1002&DEV_AA01&SUBSYS_00AA0100& REV_1007\5&14BACE15&0&0001
