Hi.
I have submitted a follow-up on my previous pr (kern/21438) concerning
4.1-rel here but it might have been considered rude by some so I will
start a fresh new thread with this since (1) a new release is coming
(yay) and (2) I do not seem to be the only one having audio problems with
-stable. A search on the freebsd.org engines does not yield any result for
"record overrun" (my problem).
Ok here we go.
Testing are all made with "rec" from the sox (12.16) package. Recording
first a simple file (8000 Hz, 8 bits, mono) works correctly. If I switch
to 16 bits, the recorded file is just empty (i.e. no sound at all). Trying
now 22050 Hz at 8 bits, mono: working correctly.
Now trying 44100 Hz at 8 bits, mono gives me:
pcm0: record overrun, dumping 44500 bytes
[...]
(about 1 warning/second) And the sample is just 8192 bytes big. CPU usage
also gets really high (almost 100%). Same with 16 bits recording at
44100Hz, mono.
Doing the same in stereo yields the predictable result:
pcm0: record overrun, dumping 89212 bytes
which is vaguely the double of mono recording overruns.
So that's about it. The message comes from line 577 in file
/sys/dev/sound/pcm/channel.c. I do not understand clearly what could be
the problem here.
The sound card is a AWE32:
sbc0: <Creative SB AWE64> at port 0x220-0x22f,0x300-0x301,0x388-0x38b irq
9 drq 0,5 on isa0
pcm0: <SB DSP 4.16> on sbc0
It's odd, however, that drq 0 thing... The system is a 4.1.1-stable dated
on 2000.10.17.
Playing hi-fi doesn't yield the same problems, on the first look, this
might be because it's using the other drq setting (???).
So that's about all I can think of now, please send in any comments or
ideas regarding this.
Here are dmesg output:
