Enabling Headphone/Mic jack


Ok, the specs:
Compaq Presario V6030
Fedora Core 6 x86_64
Onboard Audio (MCP51 I think)

And here's what I'm trying to do:
Right now the audio works great through the onboard speakers. Now, I have the nice Head/Mic Jack on the front, I want to be able to plug in a headset and get these to work. However, plugging headphones (I haven't tried the mic yet) into this jack produces:

- Audio Still plays over speakers
- Audio Does Not play out of headphones.

I took a look in KMix (Using KDE btw) and didn't see anything that immediately jumped out at me. So, my question is, how do I get this working?

1) Do I need to install anything special? Drivers, mixers? If so, how?
2) Is there a setting somewhere that I can change to redirect the output to the headphones instead of the speakers? Something in the control centre perhaps?

Ok, I noticed there were 3 other posts on the same thing here (different laptops, but same problem and same audio card). So I guess this one can die and I'll just follow the other 3. Still no answer in any of them yet though.

I just wanted to confirm I did get this working. (sort of)
I have it set up now so that I get seperate speaker/headphone controls. Not exactly what I'd hoped for, as I know it works in windows properly, but at least I can now mute the speakers and use the headphone, which is what I wanted in the first place.

It's as simple as:

1) Install alsa 1.0.13
(Well, this wasn't so simple. It's not part of the fedora repository and I had to find all the 1.0.13 rpms doing searches.)
In total, on FC6 x86_64 I had to install:

libasound2 x86_64
libasound2 i386
alsa-kmdl x86_64
alsa-lib-devel x86_64
alsa-lib x86_64
alsa-lib i386

2) edit /etc/modprobe.conf and do the following:
- options snd-hda-intel index=0
+ options snd-hda-intel index=0 disable_msi=1

Walla, all working.

(Now, if anyone knows how to either get A) power management or B) stop crashes when ctrl-alt-fx'in I'm in business!)

Ok, so ... it *was* walla, until I tried to use the mic.

Problem 1:
Now I find out the mic doesn't work. My first thought is "Hey! There's no caputre option in kmix/alsamixer!"

There is a Line In slider, and a Microphone slider, but no capture slider.

I've fired up krec and tried to record with both of these, but nothing. Can anyone provide a pointer on how to get this going?

Problem 2:
Also, I tried firing up TeamSpeak with "aoss <pathtoTS>" and I get the error:
ERROR: ld.so: object '/usr/lib64/libaoss.so.0' from LD_PRELOAD cannot be preloaded: ignored.
Then I get no sound at all in this app. So does anyone know what the problem with this might be? I *AM* using the 1.0.12 of alsa-oss and the 1.0.13 of alsa because alsa-project.org does not have a 1.0.13 version of alsa-oss yet. I don't know if it's a compatibility problem or not, but if it is - I don't get an option here as it doesn't exist!

Ok - problem 1 update: I cranked the input to 100 and ran "arecord output.wav" ... and it turns out it does work - it's just really really quiet. Is there any way that this can be cranked up? I.e. can I change my max db gain (currently 34.5)? Can I get the Mic boost option to show up? How would I do either of these?

Solved both problems last night, and one I didn't even know I had.

1) Low Sound.
Well, I don't know what to say. Using arecord I was getting barely audible sound, but once getting TS running, the sound volume was *PERFECT*. So it's an issue with arecord of some type, which I won't be using so no worries! Hurrah!

2) TeamSpeak.
This one was tricky. After finding info about running TeamSpeak on a 64-bit Gentoo I got to thinking that perhaps I needed 32-bit sound libraries. But of course trying to install alsa-oss from the i386 version conflicted with the x86_64 version (and wasn't available in the x86_64 repository so I didn't want to screw up my files). BUT! I uninstalled the 64-bit alsa-oss and installed the i386 alsa-oss -- and walla! I'm able to start my TeamSpeak *WITH* sound by editing the TeamSpeak file and using "aoss /path/to/TS". Hurrah!

3) Cedega/WoW conflicts with other programs using alsa
I found out after getting this all set up that even though I had alsa selected in Cedega (if you don't know Cedega, bear with me for a potential fix in other areas) it was exclusively locking the sound card. I found out I had to change my alsa device from "hw" to "default". Honestly, I don't know what this does, but it worked like a charm and I have sound everywhere now! Hurrah!

As a side note I did try 1.0.14rc1 to try and fix these issues and all it did was crash my machine over and over again. I had to boot into runlevel 1 and remove it in order to get my machine working. So... 1.0.13 for a while. Wish they'd make it the standard update for FC6.
