Hello. I am having a problem with severe "choppy" audio when playing back recorded video on Totem and Mythtv. On Mythtv when I play a recording for a while the chopping stops then the sound gets out of sync, and rewinding restores the sync and copping. Mythtv log shows WriteAudio: buffer underrun and repeated NVP(0): prebuffering pause errors. This is a FC12 box with Intel mobo that has Realtek ALC889A sound hardware. Mythtv is using ALSA:front for the output. I don't know about Totem because I don't see any way to configure the sound output. Sound is fine when playing CDs on Rhythmbox. Sound is also fine when I move one of the .mpg fles to a windoze box and play it there. Per suggestions I found in various posts I set EXPERIMENTALLY_ALLOW_PULSE_AUDIO=1 in the environment variable so Mythtv doesn't disable it. Have also tried the various fixes/workarounds at http://fedorasolved.org/Members/fenris02/pulseaudio-fixes-and-workarounds and http://www.pulseaudio.org/wiki/PerfectSetup and undone them because they didn't help. My ALSA audio debug output is in this post at Mythtv users http://mythtv.org/pipermail/mythtv-users/2010-January/279355.html in case that is helpful. I have researched this a lot and tried a lot of fixes, and nothing seems to be working. I am kind of at the end or my rope, so I'm hoping one of you audio wizards can suggest a fix or debugging approach. Possibly this is not a Pulseaudio problem, but even ruling that out would be very helpful. Many thanks in advance, Steve -------------- next part -------------- An HTML attachment was scrubbed...
