[mythtv-users] Anyone have a CX8800-based capture card working in MythTV?

Hi, 

Longtime lurker, first time poster. I have a MythTV version
0.18.2.20051227-1 setup in place from the instructions on Jared Wilson's
page. After much help from Jared's page, this list and a couple of other
pages, I have everything working except sound in my recordings and live TV. 

I can't run XAWTV which I assume is because I don't have a BT-based card.
When I launch it I get a pink or green screen with no sound output. It could
also be that I haven't identified the tuner correctly to the application. I
can run tvtime with no issues and Watch TV works without sound. I used to
use my onboard Intel 8x0 soundcard, but couldn't get sound in Watch TV
either. The card has an internal only 4-pin sound connector that I hooked to
Aux on both the Intel and Creative cards. I ran tvtime with that card and
did an aplay /dev/dsp and got a staticy silence. I tried moving the audio
output from the card to either the CD In or Aux In lines with no luck. With
that card I could use the alsamixer application and could assign the capture
port. With the Audigy I could not. All the time the Analog sound works fine.
I installed my Audigy 1 card and got sound in exactly the same places as
with the Intel 8x0 card. The only exception is with aplay /dev/dsp. 

With the Audigy I get:

[root at mythtv ~]# aplay /dev/dsp

Playing raw data '/dev/dsp' : Unsigned 8 bit, Rate 8000 Hz, Mono

underrun!!! (at least 9.686 ms long)

underrun!!! (at least 11.677 ms long)

underrun!!! (at least 11.724 ms long)

underrun!!! (at least 11.693 ms long)

...

I never got sound even by letting aplay run. I did get sound with an echo
one time when I accidently left the Aux-In line unmuted. Before you ask
artsd is killed. I have been searching this list and others for any help and
I have seen no one with my exact issue that didn't have a CX8800-based card.
More often than not _THIS_ card. I am at my wits end with this so in a last
ditch effort, I have included all kinds of info that people on this list or
others had asked those in my situation for in the past. Please email if you
need something else. I would especially like to hear from someone who has
either this card or another CX88

I did find this tonight:

Would that help? It's got to right? Thanks in advance
