HI all,
I thought I would open a separate thread on this issue.
When I load the* snd_hda* module and play some sound, the pulseaudio
process uses 100% of one CPU core (I have 4), however the sound is fine.
Even no playing anything, pulse is stuck at 100%
Is there anyway to get pulse to work correctly?
My hardware is an HP Desktop and sysctl reports the audio device as:
pcm0: <Realtek ALC662 (Analog 2.0+HP/2.0)> at nid 20,27 and 24,25,26 on
hdaa0
pcm1: <ATI R6xx (HDMI)> at nid 3 on hdaa1
pcm0: <ATI R6xx (HDMI)> at nid 3 on hdaa0
As far as I can tell, the Realtek device support s 44.1K,48K and 96K
sampling, so down-sampling should not be an issue.
All KDE sees is the "pulse" device with VLC backend.
Thanks,
Bernie
