What mechanism does the permission assignment use? It doesn't use
regualar unix permissions, right?
Still, while I get sound or I don't get sound it seems that pulseaudio
is accessing the device:
> sudo fuser -v /dev/dsp* /dev/snd/* /dev/seq*
Specified filename /dev/dsp* does not exist.
Specified filename /dev/seq* does not exist.
USER PID ACCESS COMMAND
/dev/snd/controlC0: boxee 2553 F.... pulseaudio
/dev/snd/pcmC0D3p: boxee 2553 F...m pulseaudio
But I have seen something odd, using another account that I have in the
box, when I do the previous, nothing comes out of it. Like if where
accessing /dev/snd/controlC0, yet I still get sound on that account the
first time I login after reboot. So, when using that account am I using
pulseaudio or alsa to access the device. My guess would be pulseaudio,
given all the configuration I had to go through in the sound
preferences, but still.
Other than that what else could I try to unravel this mistery?
