Strange... the owner is my user account and not root or audio group!!
I rebuild the alsa-driver with root all the process:
./configure --with-isapnp=no --with-cards=hda-intel
make
make install
./snddevices
Now, the owner is root. But, the change of owner didn't solve the
problem.
I tried to use the 'aplay' and I got an error about the group:
# aplay 1.wav
ALSA lib pcm_dmix.c:1101:(_snd_pcm_dmix_open) The field ipc_gid must be
a valid group (create group audio)
aplay: main:540: audio open error: Invalid argument
Creating a group audio will solve the issue here?
