live tv audio problems<BR><BR></FONT></DIV>
<P>Hi there,</P>
<P>I'm a new user of mythtv. I've recently installed mythtv_0.14 (on my
Mandrake 9.2 with kernel 2.4.22 using the GNOME desktop) and several
problems have been appearing. When using liveTV, there is a big playback
slowdown and the audio is out of sync. In this situation, mythfrontend
prompts:</P>
<P>> Audio buffer overflow, audio data lost.</P>
<P>At the begining I thought my PC configuration just couldn't do it (AMD
K6-III @400, 256 MB SDRAM), but I recorded a sample of 10 min of a TV
show, and, to my surprise, when watching it, there was no audio at all! No
need to say that the playback slowdown was also there. Moreover, while
mythbackend recording, mythfrontend tends to freeze with the minimum
overhead.</P>
<P>My livetv configuration compresses video with RTJpeg and audio with
MP3 at 33200 samples/sec. I use /dev/dsp as audio device, /dev/mixer
as audio mixer and I've linked the audio output of my MIro pctv tv card to my
sound blaster 128. I've no sync problem watching TV with xawtv. </P>
<P>I've the funny feeling that what I hear watching livetv is the sound coming
directly from my sound card instead of the livetv buffer. </P>
<P>What's the problem? It's only my poor CPU speed to blame? Any
solutions?</P>
<P>Thank you all for your answers.</P>
