Hi.

The magic in using a live and btaudio is probing your mixer first so as
to let it grab dev/dsp0 first. I'm using alsa and rh9 - pvr 250 and a
tvwonder. Nforce 2 mb. Using the live for the digital out so as to go
upstairs to the entertainment system with the picture and remote.

Here is mine (messy but hey - need to wash my car too.)

[root@linuxbox root]# cat /etc/modules.conf

Hope this helps. Forget where I got this from but it made all the
difference. Also change your setting in mythtvsetup ( to /dev/dsp1) for
your tuner.

Gary, thanks for the info, some questions follow inline with your responses.

Let the live or btaudio get the mixer? Best I can tell the live gets either
1 or 2 mixers (or more likely one goes to my onboard via audio) and btaudio
gets the next in line

# cat /var/log/messages | grep btaudio

Aug 3 22:04:01 marcus kernel: btaudio: driver version 0.7 loaded [digital]
Aug 3 22:04:01 marcus kernel: btaudio: Bt878 (rev 2) at 00:0d.1, irq: 10,

Aug 3 22:04:01 marcus kernel: btaudio: using card config "default"
Aug 3 22:04:01 marcus kernel: btaudio: registered device dsp2 [digital]]

What I find odd (and maybe this in one part of my problem) is that none of
the other dsp's being grabbed get logged to syslog

# cat /var/log/messages | grep dsp

Why do you have 2 _different_ sound-service aliases for btaudio?

What is the purpose of these 2 lines?

Well I am getting closer....

Hate to admit it but I don't know. Just works. Could be the setting of
full duplex?

The post install just means that after the via-snd is loaded, the next
step is to load the mixer settings from a file. The pre remove just
means, before the via-snd module is removed, the mixer settings are
saved to a file.




Hope this helps
