No sound on fresh install of Fedora 33 after reboot

Using the Live USB I have sound working from speakers and headphones. If I install to hard drive, I have working sound from speakers and headphones. However, once I reboot the system, the speakers no longer work and I can only get sound through the headphones. If I boot into recovery I have sound.

EDIT - it only worked once in recovery, since I rebooted, recovery has no sound either

Any ideas?

I don’t have you a solution. But maybe with this workaround you can work without recovery mode.

Thanks, but this doesn’t work.

Hallo Richard,

can you please have a look to the output of the following command?

cat /proc/asound/cards

You may see different audio devices like for example:

> 0 [PCH            ]: HDA-Intel - HDA Intel PCH
>                      HDA Intel PCH at 0xf1240000 irq 128
> 1 [Digital        ]: USB-Audio - Pre Box S2 Digital
>                      Pro-Ject Pre Box S2 Digital at usb-0000:00:14.0-4, high speed

You can have a look which are the concerning kernel modules driving the listed audio cards with:

cat /proc/asound/modules 
>  0 snd_hda_intel
>  1 snd_usb_audio

If you want to change the order use:

vi /etc/modprobe.d/sound-cards-order.conf
→ /etc/modprobe.d/sound-cards-order.conf:
options snd_usb_audio index=0
options snd_hda_intel index=1
← /etc/modprobe.d/sound-cards-order.conf:

You can have a look about stream linked devices while playing audio with:

cat /proc/asound/card0/stream0:

Pro-Ject Pre Box S2 Digital at usb-0000:00:14.0-1, high speed : USB Audio
