sound

[Patrick Dupre]

It looks like that run setfacl -m u:user1:rw /dev/snd/*
fixed the problem.

Well, it's a symptom, not the problem itself, it tells you nothing is
using snd_hda_intel on your installed system, but it is being used on
the live system.

I don't have this hardware, but see
http://www.mjmwired.net/kernel/Documentation/sound/alsa/HD-Audio-Models.txt
and step 4 of "If you have an Intel HDA card" at
http://fedorasolved.org/Members/fenris02/pulseaudio-fixes-and-workarounds
(aside: there is advice on that page to try cat-ing urandom to
/dev/dsp, isn't that potentially harmful?)

If you do "lspci -vv" on the live system you may be able to see what
option the module is being loaded with or selecting itself there. In
which case try that with the installed system. If that works then you
should probably file a bug against the snd_hda_intel module in Fedora
that the auto selection isn't working for your system. If aplay isn't
working it's an alsa problem, in which case your next step is to take
it to the alsa mailing list as there will almost certainly be someone
there who can figure out what the problem is.
