Audio permission weirdness

[Luis Falcon <falcon%gnuhealth.org@localhost>]

Good morning, everyone!

When trying to access the default audio device (/dev/audio1) I get an
"operation not permitted" error.

It does not happen with the HDMI device (/dev/audio0) or when the device
is accessed by root.

File permission masks are the same for the devices, and no process seems
to be locking the file.

I'm pasting some logs that might be of help.

Have a great weekend!
Luis
