Audio disabled on some boots

[Beerislife]

Since I added an MSI Geforce GTX-1050ti video card to my system I've been having a small problem on some boots where audio is not activated. A reboot usually fixes it. It's like the onboard AMD audio (preferred) and the Nvidia drivers are fighting for superiority and neither win!

I'd like to somehow disable the Nvidia audio, my HDMI monitor does not have speakers! I use a pair of Bose powered speakers hooked up to the audio out jack!

This is how it should be (and is right now) Sometimes both audio devices are off at boot and there is no setting to enable them.

Same here

I have the exactly the same problem since 20.10, with AMD onboard audio but no nVidia HW in my system. I found three differences in lsmod after a boot without audio compared to a boot with audio:

Audio ok:

snd_hda_intel          53248  [B][COLOR=#ff0000]6[/COLOR][/B] snd_hda_codec_generic,snd_hda_intel,snd_hda_codec,snd_hda_codec_realtek
snd_pcm               118784  [B][COLOR=#ff0000]4[/COLOR][/B] snd_hda_intel,snd_hda_codec,snd_hda_core
snd                    94208  [B][COLOR=#ff0000]23[/COLOR][/B] snd_hda_codec_generic,snd_seq,snd_seq_device,snd_hwdep,snd_hda_intel,snd_hda_codec,snd_hda_codec_realtek,snd_timer,snd_pcm,snd_rawmidi

No audio:

snd_hda_intel          53248  [B][COLOR=#ff0000]1[/COLOR][/B]
snd_pcm               118784  [B][COLOR=#ff0000]3[/COLOR][/B] snd_hda_intel,snd_hda_codec,snd_hda_core
snd                    94208  [B][COLOR=#ff0000]14[/COLOR][/B] snd_hda_codec_generic,snd_seq,snd_seq_device,snd_hwdep,snd_hda_intel,snd_hda_codec,snd_hda_codec_realtek,snd_timer,snd_pcm,snd_rawmidi

Does anyone have an idea what this could be?

Just found that

[FONT=sans-serif]systemctl --user restart pulseaudio
[/FONT]

will get my sound back after a boot without sound. Still don't know how to permanently fix it though...
