magic btaudio incantation ;-)

Hmm, I've never had very good results with btaudio, however I finally have it
so the driver loads automatically and mythtv uses btaudio for recording.
However I can't seem to get the btaudio mixer device to show up reliably.
Either btaudio works but no mixer device or vice versa. Can one of the other
btaudio users check out this modules.conf and tell me if they can see where I
am going wrong?

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[at]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: 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

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?

From the archives

http://www.gossamer-threads.com/archive/MythTV_C2/Users_F11/bttv_loading_problem_fixed,_but_wont_load_automatically_now._P65326/

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
