<P>Hello Peter</P>
<P>I had my rounds with what I think is the same card, and let me tell you
that in the end I gave up and bought another card.</P>
<P>Anyway, I do remember that the driver's author say the sound is still in
progress. </P>
<P>Also, I don't know why, I could get sound in tvtime IF I chose mono and
did some magic with the alsa controls, muting some channels that I would
think they should be unmuted.</P>
<P>I never got the card to work well with mythtv, sorry about that. </P>
<P>Sorry that I can't help much more.</P>

[mythtv-users] WinTV Go sound issues...<BR><BR></FONT></DIV><!-- Converted
from text/rtf format -->
<P><FONT face=Arial size=2>Hi all,</FONT> </P>
<P><FONT face=Arial size=2>I'm setting up MythTV 0.16 on a friend's box. It
has a recent WinTV Go card with a Conexant chip so I'm using the cx8800
kernel module.</FONT></P>
<P><FONT face=Arial size=2>After fiddling a bit with the hue and color
settings I got video playback and recording just fine. I wish I could say
the same about audio...</FONT></P>
<P><FONT face=Arial size=2>This card has a audio line-out. For use in
MythTV this line-out is connected to the line-in of the onboard sound
card.</FONT> <BR><FONT face=Arial size=2>I'm also using tvtime to test the
drivers. When using tvtime I connect the line-out of the WinTV Go card
directly to the amplifier of my sound system.</FONT></P>
<P><FONT face=Arial size=2>I've tried both the cx8800 v4l driver with
kernel 2.6.9 and the snapshot from </FONT><A
href="http://dl.bytesex.org/cvs-snapshots/video4linux-20041217-141849.tar.gz
"><U><FONT face=Arial color=#0000ff
size=2>http://dl.bytesex.org/cvs-snapshots/video4linux-20041217-141849.tar.g
z</FONT></U></A><FONT face=Arial size=2>.</FONT></P>
<P><FONT face=Arial size=2>Here are my experiences:</FONT> </P>
<P><FONT face=Arial size=2>- tvtime (non-buffered playback) works perfect
with both the 2.6.9 drivers and latest snapshot V4L drivers. Line-out of
the WinTV Go card is connected directly to my sound system.</FONT></P>
<P><FONT face=Arial size=2>- mythtv with kernel 2.6.9 V4L drivers: I can't
get any sound out of this. I can change channels, playback and record
video, but without audio.</FONT></P>
<P><FONT face=Arial size=2>- mythtv with V4L snapshot drivers:The same as
with kernel 2.6.9 drivers, except that with these drivers a radio device is
now also detected while loading the drivers. When I'm doing TV playback on
mythtv (without sound), and I do a 'cat /dev/v4l/radio0', the tuned
frequency of the card changes, mythtv playback switches to static, and i
_do_ get static out of the speakers all of a sudden. Note that in this case
the line-out of the WinTV Go card is connected to the line-in of the sound
card. When I now change the channel in mythtv, I get normal tv playback
_with_ audio. Video and audio are perfectly in sync. I can change channels
and audio keeps on working. If I now press the 'r' key on the keyboard to
record the live stream audio get's turned off again. I'm watching the tv
stream without sound. Also if I exit live playback and play back the
recording stream from the media library, I see that no sound is being
recorded. If I do 'cat /dev/v4l/radio0' again, I can watch live (buffered)
TV again with sound.</FONT></P>
<P><FONT face=Arial size=2>There is no radio device detected with the
kernel 2.6.9 cx8800 V4L driver so I can't try this with those
drivers</FONT> <BR><FONT face=Arial size=2>As you can see in the dmesg
output below, with the snapshot drivers a radio device is created and not
with the kernel 2.6.9 drivers.</FONT></P>
<P><FONT face=Arial size=2>Also, the snapshot drivers detect a MSP3425
audio processor but the msp3400.ko module is not needed for audio to
work.</FONT> </P>
<P><FONT face=Arial size=2>Since unbuffered TV playback in tvtime is
working fine and via 'cat /dev/v4l/radio0' I can get sound output on the
WinTV Go card enabled in MythTV, I suppose the problem lies in MythTV
itself.</FONT></P>
<P><FONT face=Arial size=2>Has anybody seen this before? Is this card maybe
not yet supported in MythTV? Or maybe the CVS version of MythTV has some
fixes for this?</FONT></P>
