geo_c,

After installing 5.20 I started having problems with it. I don't recall the specifics, only that I decided to get rid of it. And I did.

thanks Bruce

that's not the first time it went buggy on me either

it was rather convenient though

to have that master volume slider that stays open until you turn it off

great while doing multimedia work.

When you use alsaconf , older alsaconf wrote to /etc/modprobe.conf . Newer alsaconf might write to /etc/modprobe.d/modprobe.conf .

In fact the drivers write files into /dev . Some seems not to use /dev/snd . Instead they write directly into /dev . The udevd should take care of the /dev for attached usb and sound_modules .

You can look for permissions using
Code:
ls -l /dev/snd*
ls -l /dev/pcm*
ls -l /dev/seq*
ls -l /dev/*midi*
ls -l /dev/*mix*
ls -l /dev/con*

and some more .

Retrovol is unfortunately programmed to crash , if some values can't be obtained .
If you `aplay /usr/share/audio/2barks.au` , you would get a similar errormessage .

You can try to delete some c[har-device] files @/dev with same major, minor numbers or without right permissions . Check , if they are in both dirs : /dev and /dev/snd , which they shouldn't . Also try deleting some soundcard entries in /etc/asound.state .

/etc/init.d/alsa would show some addditional commands like `alsactl -f /etc/asound.state restore`

thanks Karl.
my limited knowledge allows me to only vaguely guess what
dev/snd actually does.

it sounds as though an entry in dev/snd is where a program accesses a
standard device such as usb audio or midi channels.

i'm always keen to learn what is really going on
at the same time I'm having too much fun with my puppy setup at the
moment to risk breaking the alsa driver for the sake of the retrovol.
