I have a F23 system which I use as a HTPC and occasionally the audio reverts from hdmi2 in the devices to the on-board stereo sound card.
Anyone have any ideas?
The kernel loads drivers in parallel, so sometimes the order of audio devices is different because of different load order. You can put a file in /etc/modprobe.d specifying the position of the devices, and this shouldn't happen any more.
A sample of what I use in a file called soundcard.conf.
options snd cards_limit=8 options slots=snd-hda-intel,snd-ice1724,snd-ca0106,snd-hda-intel alias snd-card-0 snd-hda-intel id="SB" options snd-hda-intel index=0 alias snd-card-1 snd-ca0106 id="CA0106" options snd-ca0106 index=1 alias snd-card-2 snd-ice1724 id="Revolution51" options snd-ice1724 index=2 #alias snd-card-3 snd-cmipci #options snd_cmipci index=3 alias snd-card-3 snd-hda-intel id="HDMI" options snd-hda-intel index=3 alias snd-card-7 snd-usb-audio options snd-usb-audio index=7
You'll probably have to tweak it, a search should find something closer to your setup.
