ALSA and microphone

Llama · 2008-12-23 09:54:42

Hi,

I can't make my mike behave. Manipulations with Mic/Boost bring some auditory artifacts, but no real work. No personal experience, not much on the Web in the line of how-tos. Any link on ALSA and mike, especially for dummies, is welcome .

Might not be that easy I'm afraid .... I'm having trouble getting my headset to work with the card on my desktop, capture from mic has artifacts with alsa (periodic null/zero samples) and I haven't been able to sort it out and I still didn't have time to figure out how to make it work with oss. In my experience alsa either works very well or very bad .... I'm starting to hate alsa

What am I to do, then? Give up mike ? There must be some approach, some alternative... FOSS is all about it, right ?

is your mike inbuild in a laptop or a desktop pc? if a laptop, try setting options snd-hda-intel model=modelofyourlaptop in /etc/modprobe.d/sound

It's a part of a headset. That is, an ordinary mike, to be plugged into the sound card.

In my case sound capture from mic sucks big time with alsa on my laptop (headset mic, didn't even bother to try built-in one as they all suck), yesterday I have sorted out how to make it work perfectly in OSS (a lot more of controls there, lots of trial and error).
In my desktop with a non HD Audio audio controller things work ok though.
As a bonus, playback quality is much better with OSS than it is with alsa.
OSS isn't as convenient as ALSA when I my usb headset though but I guess I will learn to live with that.
For the record setting "options snd-hda-intel model=modelofyourlaptop" in /etc/modprobe.conf only fixed the auto mute the speakers when I plug-in a headset or headphones .... maybe it broke sound capture ... pfff ALSA should be named ALSH as in Advanced Linux Sound Headache.
Sorry for the rant but so far I've seen people complaining a lot more about alsa than I've seen complaining about oss and from personal experience I see why.

I've taken a look at my etc/rc.conf:

MODULES=(vboxdrv fuse 8139cp 8139too mii rtl8187 !ndiswrapper snd-mixer-oss snd-pcm-oss snd-hwdep snd-page-alloc snd-pcm snd-timer snd snd-hda-intel soundcore)

It looks like there are too many sound-related identifiers ... I can't remember putting them in; is there a way to sort them out? Could they be a problem?

R00KIE · 2009-01-16 11:36:07

You could try

MODULES=(vboxdrv fuse 8139cp 8139too mii rtl8187 !ndiswrapper )

and let udev sort it all out .... not sure it will help though ... but its worth a try.

The short modules list works just as the long one . No better, no worse...

Llama · 2009-04-19 23:23:28

There's a bit of relevant documentation here, they say .

The hardware:

Card: HDA Intel
Chip: Realtek ALC660-VD

Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

Any ideas how to use the doc?

Unless things have changed I guess you will have trouble making that work properly.
My notebook has the same audio codec, only the controller is different (ATI Technologies Inc SBx00 Azalia (Intel HDA)).
Now I have it working properly but with OSS not ALSA.
