Hello,
i found problem in OpenBSD i386 3.5 stable, this problem also exist in 3.4
stable.
--- dmesg part ---
emu0 at pci2 dev 11 function 0 "Creative Labs SoundBlaster Live" rev 0x0a:
irq 5
ac97: codec id 0x83847608 (SigmaTel STAC9708/11)
ac97: codec features 18 bit DAC, 18 bit ADC, SigmaTel 3D
audio0 at emu0
"Creative Labs SoundBlaster Live Digital Input" rev 0x0a at pci2 dev 11
function
1 not configured
--- dmesg end --
--- mixerctl --

$ cat /etc/mixerctl.conf
inputs.mic=7
inputs.mic.mute=on
record.volume=15,15
record.volume.mute=on
---
(I added in /etc/rc autoapplay)

By default microphone is mute, but when play any audio file
mic volume is on and if speakers volume is center (from 1 min to 8 max,
now is 4, sorry of my bad english)
i hear terabble noise.

$ mixerctl -w inputs.mic.mute=on
inputs.mic.mute: off -> on
$ mixerctl inputs.mic.mute
inputs.mic.mute=on
$ play .ickle/Sounds/Global.wav
$ mixerctl inputs.mic.mute
inputs.mic.mute=off


Any body know how to resolve this problem?

Regards,
Condor

Are you *really* sure it's the OS ?

I'm playing my techno collection at this very moment and the
sound quality is perfect. (as in *Cristal Clear*) no noise at all.
(Some might call it noise though, you know 'old people')
But seriously, works fine here with 3.4 & 3.5
My mic doesn't have your issues either.

Hmz.. what are the specs of your machine ? (Mem/Cpu)
Did you try loading your bios to it's default configuration ?

| Condor

Good luck.

May be in your system this problem does't exist.

I now found problem.
The problem is that my microphone is voluminous and get
all noises from my room and insert into card.
I know this problem exist in windows too, the microphone
cable must be swich off from card or mute (i use mute in windows) when
the micrphone is too close to speakers.

If you are *really* sure, use the `sendbug` tool.

Exacly ! Same setup but no problems.
Look further.

Works fine here.
(On Win2K/XP / Linux 2.4/6 / OpenBSD v3.*)

Caused by electrical interference.

Buy a decent Mic, that reduces the distortions a lot.
And actually try what i said in the first post. (bios)
for the mute issue.

I don't want to buy a new mic.
I want to resolve this problem, why mic.mute when playing audio is switching
to on ?
and yes, i tryed to load bios to default configuration. No effect.
