Hello,

I have an IBM T41 laptop with an Intel8x0 built-in sound card that
generally works fine under alsa.  I have been trying very hard to get it
to play friendly with mythTV and my Plextor PX-TV402U-NA.  The developer
of the Plextor Linux driver wrote me this:

*QUOTE*-------------------
>From your previous posts, it looks like card 0 is your built-in sound
and card 1 is the ConvertX.  So you should be capturing from hw:1 and
playing back to hw:0.  Make sure you use 48000 KHz with 2 channels.

There's no mixer in the GO7007 driver and there's only one input, so you
shouldn't have any trouble getting audio capture configured correctly.
If you're using the settings above and it still doesn't work, it's
probably an issue with getting Myth to talk to your playback sound card.

Also, if you're testing outside MythTV, keep in mind that you won't be
able to capture sound unless the video encoder is running.  -Nathan

At present, I have run alsaconf and setup the card such that my
/etc/modules.d/alsa effectively reads:

-----------------------
...

alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.

alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss

alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-intel8x0

...
-----------------------

At the same time, my .asoundrc reads:

-----------------------
# cat ~/.asoundrc
pcm.intel8x0 {
        type hw
        card 0
}

ctl.intel8x0 {
        type hw
        card 0
}
------------------------

I have verified that the capture device works under Windows.  When
running under MythTV, I can get some relevant audio (mono, 8000Hz) via
$ aplay /dev/audio1.

I've done some reading on the .asoundrc file, but don't see how I should
set it up for the capture device nor how I can pipe from one device to
another.  I'm hoping for some help.  I'm willing to try ideas all day
PST in order to get this working.

At this point, I'm guessing I should have at least:

-----------------------
# sound card
pcm.intel8x0 {
        type hw
        card 0
}
ctl.intel8x0 {
        type hw
        card 0
}

# capture device
pcm.plextor {
        type hw
        card 1
}
ctl.plextor {
        type hw
        card 1
}
------------------------


Thank you,
Phil
