[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.gz</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>
<P><FONT face=Arial size=2>Thanks & kind regards,</FONT> <BR><FONT
