thanks for taking the time to help.
I am trying to install Mythtv 0.11 on gentoo 1.4
I am using a Hauppauge WinTV-dbx model 401 which is suppost to be the only
card that works reliably with btaudio. My sound card is built into my Asus
A7N8X deluxe mother board.
the install and initial setup (mysql etc.) gos smoothly I setup the backend
via mythsetup and start mythbackend.
When I go into the mythfrontend and go to setup I can only select from two
audio output devices. /dev/dsp and /dev/dsp1 if I choose ether of these I get
kicked out the moment I try to go into live TV.
My sound works fine (i can listen to music and the like) in kde but I can't
figure out how to get myth to use my sound card, now might be a good time to
mention I'm using alsa and I loaded alsa-oss below is the error I get from
mythfrontend:
Opening OSS audio device '/dev/sound/dsp'.
ERROR: something is currently using: /dev/sound/dsp
Fix this, then run mythfrontend again
I'm guessing this is because I'm using /dev/dsp as my Audio Device in
mythsetup and as my Audio Output Device in mythfrontend - setup
but what should my Audio Device be?
by the way if I open xawtv I get good video but no audio (this is because I'm
using btaudio and have not hooked up a patch cable) if I type
aplay -f S16_LE -c2 -r32000 /dev/dsp I get the audio fine.
so I know btaudio works and the video works. just not in mythtv
how can I find out what device in /dev/ is allowing me to hear sound?
below I will list my modules.conf, and the usefull bits of of dmesg and lspci
