Hi !
I'm trying to get rid of my sound card lags (snd_hda driver). The
problem is: the sound is often stopping for a small amount of time. I'm
not having high load average, about 0.5 - 0.8.
I've tried playing with sysctl knobs. Current values are :
sysctl -a | grep snd
hw.snd.report_soft_formats: 1
hw.snd.latency: 8
hw.snd.latency_profile: 1
hw.snd.feeder_buffersize: 65535
hw.snd.feeder_rate_min: 1
hw.snd.feeder_rate_max: 2016000
hw.snd.feeder_rate_round: 25
hw.snd.verbose: 1
hw.snd.default_unit: 0
hw.snd.maxautovchans: 8
my hardware from dmesg :
dmesg | grep pcm
pcm0: <NVidia MCP51 High Definition Audio Controller> mem
0xfe024000-0xfe027fff irq 21 at device 16.1 on pci0
pcm0: <HDA Codec: Analog Device AD1986A>
pcm0: <HDA Driver Revision: 20070128_0039>
