folks, i am having a difficult time getting the audio to work on my
remote (diskless) frontend.
i believe i have alsa working correctly, as alsaplayer will play just
fine. if i set the audio output
device to "ALSA:default" and the mixer device to "default" i get the
message: "Unable to set ALSA parameters"
on the screen and mythfrontend reports:
2005-12-02 09:50:45.098 Using protocol version 15
2005-12-02 09:50:45.845 Killing AudioOutputDSP

Invalid argument
2005-12-02 09:50:45.866 Unable to set ALSA parameters
if i set the audio output device to /dev/dsp and the mixer device to
/dev/mixer, and try to watch tv, i get no sound
but the speakers on the tv will click once and mythfrontend reports the
following:
2005-12-02 09:54:36.285 Using protocol version 15

and then keeps repeating the "free space avail" message over and over
again...
i am running my own build of the 0.18.1 tarball on debian sarge using a
2.6.11.7 kernel i also built myself.
the sound drivers are compiled in as modules rather than into the
kernel, as i read somewhere that might
makes a difference. i have alsa oss emulation tuned on but not oss
itself. an lsmod shows the following:

i have read as much documentation (both mythtv and alsa) as i can find,
and have been troubleshooting
this for days now. any help from the group would be very much
appreciated. i am new to the group
but have been playing with mythtv for a few months now. i also want to
express my appreciation for
mythtv to everyone that contributes to it. it is simply a wonderful
suite of programs.
thanks and best regards,
daryl
