Sound modules load in random order

[ismell]

In the latest builds snd-usb-audio randomly loads into slot 0 or 1 when in the alsa-base.conf it has the index listed as -2.
This causes issues because it's expected that snd-hda-intel will be in slot 0. Adding indexes or even using the new options snd slots snd-intel-hda, snd-usb-audio option does not do anything.I think this is the reason sound only works 50% of the time on some boxes.

Don't know how to fix it yet, but looking into it.

Hi ismell,

can we close this for now?

[ismell]

I'll double check on my latest dev build and let you know if it's been fixed.

I don't personally need usb audio so I have it blacklisted. Though a new user might find it confusing if the sound randomly stops working for them.

On a different note I also tried using the drop downs in the XBMC audio settings to pick hdmi - NVidia -7 and I got the following:
18:30:15 T:140705320756992 ERROR: Initialize - failed to open custom device plug:'hdmi:CARD=NVidia,DEV=7' (error:No such file or directory), retry with default hdmi:CARD=NVidia,DEV=7
18:30:15 T:140705320756992 ERROR: Initialize - pcm_open_lconf, alsa error: -2 - No such file or directory

If that was to work correctly I don't think it would matter what order the modules loaded because they would be loaded by name then.

I'm running OpenELEC 1.95.4 in a Jetway ION2 computer and this issue hasn't been solved yet.

[ismell]

For now just do the following
echo 'blacklist snd_usb_audio' >> ~/.config/modprobe.d/blacklist.conf

closing for now, if the problem still exist please open a new report
