Is it me? Or does mythmusic only work on oss?
I use alsa:spdif for mythtv, so when I use mythmusic I have to switch to my
analog output before I can hear audio!
I had problems getting mythmusic to play through spdif even after following the DigitalSound HOWTO at
http://www.mythtv.info/moin.cgi/DigitalSoundHowTo
I used the more advanced .asoundrc file and uncommented the 14th line slave.pcm "dmix-digital"
I'm sorry I can't remember for certain which one of these I'm currently using
/dev/adsp
or
ALSA:dmix-digital
or
alas:dmix-digital
I can check tonight if you haven't got it working. However, the key for my system was adding the following line to modules.conf or modprobe.conf depending on whether you're using a 2.6 or 2.4 kernel. This number may be different depending on your sound card.
options snd-pcm-oss adsp_map=2
You should be able to verify the number of your spdif output by cat /proc/asound/pcm
00-00: Intel ICH : NVidia nForce2 : playback 1 : capture 1 00-01: Intel ICH - MIC ADC : NVidia nForce2 - MIC ADC : capture 1 00-02: Intel ICH - IEC958 : NVidia nForce2 - IEC958 : playback 1
The IEC958 line is the spdif on my nForce2 builtin audio, so I set adsp_map=2
Everything was working fine with the above config until I upgraded from redhat 9 to fedore core 3. I got a bunch of permission in mythtv about not being able to open the audio devs. I fixed this by editing /etc/udev/permissions.d/50-udev.permissions. I changed the group permission on all of the audio stuff to my mythtv group. I haven't seen this mentioned before, but it fixed my situation.
