Recorded shows audio sync problems.<br></div></font><br></div><div><div></div><div class="h5">
<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>> 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
problems, it looks and<br>> sounds perfectly, except for the growing sync
loose.<br><br></div></div>What type of capture card are you using? Do you
see any<br>audio/video/sync messages in your mythfrontend
logfile?<br><br>Nick<br><font color="#888888"><br>--<br>Nick
