Hmm...things you can try: 1) Tell pulseaudio not to use the saa7134-alsa soundcard (click on sound preferences (top panel, on the right, near the clock) and disable saa7134 soundcard). 2) Run "cat /proc/asound/card" or "arecord -l" and make sure you're using the right device on the MPlayer command line (the "adevice=hw.1,0" part). 3) Add "audiorate=32000" like this: mplayer tv:// -tv driver=v4l2:device=/dev/video0:norm=PAL:input=0:alsa:adevice=hw.1,0:amode=1:audiorate=32000:immediatemode=0:chanlist=europe-west 4) See if MPlayer reports any error with alsa/audio. Lastly, I think tvtime only works with a patch audio cable (which is cable that connects the tv-card "audio out" to the soundcard "line in"). So you can try to start tvtime and then run: arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | aplay - this way you record from the saa7134 audio device and play it back to your speakers. > >> (make sure you select the right alsa device in adevice=) >> >> The wiki has a good page about MPlayer: >> >> http://www.linuxtv.org/wiki/index.php/MPlayer >> >> and of course the MPlayer man page explain all the options too. >> >> These pages are also useful (but some things might be a bit outdated): >> >> http://www.linuxtv.org/wiki/index.php/ASUS_My_Cinema-P7131_Hybrid >> http://www.linuxtv.org/wiki/index.php/Saa7134-alsa >> >> I hope this can help you and others reading this ML. >> >> Regards, >> Giorgio Vazzana >> >>> Thanks >>> -- >>> Dejan Rodiger > Cheers, Giorgio Vazzana -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
