Hi,
attached are the config descriptors and the device dump of two uaudio=20=20
devices.=20Both exhibit distorted audio output. It sounds a little bit=20=
=20
like=20clipping / not feeding enough samples fast enough...
I played around with dev.pcm.2.bitperfect=3D1, dev.pcm.2.play.vchans=3D0,=
=20=20
dev.pcm.2.play.vchanrate=20and hw.snd.latency=3D1...10.
At some point vchanrate doesn't work anymore, it always stays at 4.0=20=20
audio,=20even when trying to go back to 2.0. I have to usbconfig reset=20=
=20
the=20device.
Sometimes (rarely) when playing around I get clear audio output, but=20=20
when=20I try to reproduce it (going back to default value for the last=20=
=20
sysctl=20setting and then going back again to the same setting again),=20=
=20
the=20audio is distorted again.
To me it sounds like some kind of buffer is not big enough or the data=20=
=20
is=20not delivered fast enough to the uaudio device. But this is a=20=20
dual-socket=20system with:
CPU: Intel(R) Xeon(R) CPU E5620 @ 2.40GHz (2133.36-MHz=20=
=20
K8-class=20CPU)
FreeBSD/SMP: Multiprocessor System Detected: 16 CPUs
FreeBSD/SMP: 2 package(s) x 4 core(s) x 2 hardware threads
And while playing around with uaudio the system has a load of around=20=20
1,=20so I would expect CPU/RAM is not an issue here.
I would expect that just attaching an uaudio device like those and=20=20
using=20madplay/mpg123 would just work (not looking at digital output=20=20
and=205.1/7.1 output for video, just the basics like stereo output of=20=20
MP3).=20So either I do something fundamentally wrong and would need a=20=20
hint=20with the cluebat, or I would need some description how to debug=20=
=20
this=20further from the USB side...
Bye,
Alexander.
