First off, I'd like to thank everyone that helped me get LIRC
working with the PVR150. It works like a dream now. The problem
that I have now seems like it may be a permission issue but I'm not
sure where. I can't use ALSA if I'm logged in as the mythtv user but
it works fine if I'm logged in as root. Here is what I get as root
and as mythtv:
[EMAIL PROTECTED] /]# aplay /usr/share/sounds/KDE_Startup.wav
Playing WAVE '/usr/share/sounds/KDE_Startup.wav' : Signed 16 bit
Little Endian, Rate 22050 Hz, Mono
[EMAIL PROTECTED] /]# exit
exit
[EMAIL PROTECTED] /]$ aplay /usr/share/sounds/KDE_Startup.wav
ALSA lib pcm_dmix.c:797:(snd_pcm_dmix_open) unable to create IPC shm
instance
aplay: main:533: audio open error: Permission denied
Here are the permissions of /dev/audio and /dev/dsp:
[EMAIL PROTECTED] /]$ ls -l /dev/au*
crwxrwxrwx 1 mythtv root 14, 4 Oct 18 03:24 /dev/audio
[EMAIL PROTECTED] /]$ ls -l /dev/dsp
crwxrwxrwx 1 mythtv root 14, 3 Oct 18 03:24 /dev/dsp
Any ideas????
ls -al /dev/snd
to show ALSA devices.
Most likely you'll see a group called "audio" or something. Then,
just add mythtv user to the audio group. If not (i.e. if owner and
group are root), fix the permissions (probably in udev scripts--
http://www.reactivated.net/writing_udev_rules.html ).

Its really odd. Now that I've changed the group on '/dev/snd/*',
'/dev/shm', '/dev/dsp', and '/dev/audio' to mythtv, everything works
fine. Until I root plays a sound and then I'm right back to the above
error msg, unable to create IPC shm instance.
Why would this be? root must be doing something to the devices when it
plays a sound. Any ideas?
Thanks for the above help. At least I've gotten this far.
