Comment 7 for bug 110900

I have the same problem after updating from Edgy to Feisty. Neither installs have or had a /etc/asound.conf and creating one did not help. Otherwise the sound works for CD's and TVTime and listening to internet radio. It is just system sounds that don't run for the logged in user. If I run aplay /usr/share/sounds/login.wav as root the login wav plays just fine but if I run it as a user I get the error reported at the beginning of the chain above.
As root
aplay /usr/share/sounds/login.wav
Playing WAVE '/usr/share/sounds/login.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

When I run it as my user ID I get:
aplay /usr/share/sounds/login.wav
ALSA lib confmisc.c:1105snd_func_refer) Unable to find definition 'defaults.pcm.dmix_format'
ALSA lib conf.c:3500_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:3957snd_config_expand) Args evaluate error: No such file or directory
ALSA lib pcm.c:2145snd_pcm_open_noupdate) Unknown PCM dmix:VT82xx
aplay: main:550: audio open error: No such file or directory

My user ID is in the audio group.
Anybody have any ideas?
