Re: ALSA setup fails for user
I apologize if this message goes out twice. The only way I can post to
the debian-user list is via smtp, but I normally read it in the
newsgroup. Too overwhelmed with other problems to be able to turn my
attention to this issue.

Thanks for your willingness to help.

It's simple things like this that cause me to go off track. No wonder
I concluded that changing /dev/dsp0 had no effect ;-(. Do you know
what interface is being used? Perhaps the various files in /dev/snd/.

So it seems, but the plot thickens.

Actually, the reconfiguration did the trick, partly, and I have had
the same experience as before. For some reason, perhaps with a reboot,
sound does not work until I reconfigure ALSA.

My version of the packages is current for stable. I'm having other
problems that may be resolved if I upgrade my kernel, but can't risk
At this point, I can get sound with these:
$ gxine test.wmv $ aplay test.wav
but two issues remain. One is trying to play a midi file. I find that
aplaymidi and pmidi give about the same results, which is that I must
supply an ALSA output port. When I do
$ aplaymidi -l
Port Client name Port name
64:0 Audigy MPU-401 (UART) - Rawmidi Audigy MPU-401 (UART)
64:32 Audigy MPU-401 (UART) - Rawmidi Audigy MPU-401 #2
I'd assume that 64 is the port (the :0 part optional), and so this
$ aplayer -p 64 test.mid
but this just hangs. I could alsop define the environment variable
ALSA_OUTPUT_PORTS, but how? I have no ~/.asoundrc, and the only alsa
configuration file seems to be /usr/share/alsa/alsa.conf, but that
does not look like file meant to be edited.
The second issue is xmms. If I do:
$ xmms test.wav
Message: device: default
Message: alsa mixer timed out
And no sound. In ~/.xmms/config I have:
What is the "default device"? The mixer (I've no problems with
alsa-mixer)? A /dev interface (and if so, which one?). Or the actual
card (Audigy MPU-401)? Or a mixer-card? Or what may be a device
inteface such as /dev/snd/pcmC0D0?
It may be simply that the config file needs modification, and after a
reboot I'm loosing the custom configuration I create by running
alsaconf. I suspect I need /etc/asound.conf or ~/.asoundrc. I'm not
sure what to put in them and their syntax.
