Pulseaudio lags / delays

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I'm trying to play video with the new pulseaudio (as system wide daemon)
and I see that audio lags about 0.3 - 0.5 secs on the motherboard provided
integrated soundcard.

Using debian, pulseaudio 12.0-1

the earlier major version worked well with the same machine. If you need
any further, please let me know.

Thanks a lot,

Tamas
