Ubuntu Lucid / PulseAudio Alsa-Plugin : 2 sec delay
Binary package hint: pulseaudio
I installed a fresh Ubuntu Lucid, and updated from Lucid-proposed.
Kernel is 2.6.32-22-generic. Did not installed anything particular.
Didn't add any fancy repo or ppa...
I'm using xdtv to watch tv, and a descrambler based on alsa.
Works nice in Karmic and Jaunty. No noticable latency...
But in Lucid I get a 2 sec delay between audio and video.
with pulseaudio in verbose mode, I notice very few differences
between Lucid and Karmic, when I launch the tv program:
The main difference is the order in which "source alsa_input"
and "Sink alsa_output" are processed. And there's a 2000 ms
latency request here that seems to be my problem.
I tried many things from related bugs-reports I found around here
starting with checking openal1 from proposed, re-compiling alsa from source,
using kernel2.34, audio-dev-team ppa or ricotz ppa for newer alsa and pulseaudio
None of which succeeded...
Anyone has a clue ?
This is my first bug report on launchpad, so I'm sorry if I mispost here or mis-whatever
And sorry also for my poor english !
PS : my soundboard is an AC'97, always worked perfectly 9.10, 9.04 8.10...etc
