Discussion about mythtv<BR><B>Subject:</B> Re: [mythtv-users] LiveTV and
Recorded shows audio sync problems.<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>I'm using an Analog V4l capture card, which is an Encore ENLTV-FM with
chipset saa7134 (philips i think).</DIV>
<DIV>Audio out on the capture card goes to my sound card line in with a cable.
Alsa is set to capture from line in, and line in is muted so it goes through
mythtv.</DIV>
<DIV><BR></DIV>
<DIV>If i start livetv and just watch, i don't see any new messages at the
log. The sound just starts delaying gradually. If i check the recording later,
it has the same delay, so it looks like the delay is being recorded, not just
a problem at playing back.</DIV>
<DIV><BR></DIV>
<DIV>Anyway, if the info helps, i can see some bad messages when changing
channels. Like these:</DIV>
<DIV><I>----------------------------------------------------------------------</I></DIV>
<DIV><I>2010-01-22 15:23:01.711 WriteAudio: buffer underrun</I></DIV>
<DIV><I>2010-01-22 15:23:07.495 WriteAudio: buffer underrun</I></DIV>
<DIV><I>2010-01-22 15:23:07.735 NVP(0): prebuffering pause</I></DIV>
<DIV><I>----------------------------------------------------------------------</I></DIV>
<DIV><BR></DIV>
<DIV>So, when i change channels, i get these messages, the video starts
showing but the audio starts 1 or 2 seconds later, and late. </DIV>
<DIV>Maybe this problem is related with the gradual delay, and changing
channels just makes it stall. But again, it happens gradually too without
touching anything and without any message.</DIV>
<DIV><BR></DIV>
<DIV>Thanks,</DIV>
<DIV>Sergio.</DIV>

<DIV class=h5>> Hi guys, i've been googling and reading lots of posts
trying to solve this<BR>> problem, but no luck so far.<BR>> I have
mythtv installed in Ubuntu 9.10 (Karmic Koala) using the package<BR>>
provided in the Ubuntu repository.<BR>> Mythtv version there is
.22<BR>> My problem is that audio/video sync starts ok , but sound gets
delayed<BR>> gradually, more and more. After an hour watching tv or
recording a show the<BR>> delay in sound may reach more than 5
seconds.<BR>> Im runing backend and frontend on the same Core 2 Duo PC
with 2 GB ram. CPU2<BR>> shows high usage when watching tv, but CPU1 is
almost free.<BR>> I don't see any video or audio jumps , nor quality

loose.<BR><BR></DIV></DIV>What type of capture card are you using? Do you
