The chip is reported as a 'SigmaTel STAC9750/51' and the card is 'Sound Blaster Audigy2'. Unmuting the Digital Output setting produces a buzzing; I'm guessing the digital signal. But muted, I get silence, regardless of what I do with the other settings.

In the gnome volume control panel I also get a whole bunch of EMU10K1 PCM sliders.

Thanks for the help!

Have you tried unmuting everything except the external amplifier option? What kind of speaker setup do you have, and if you have a mic how close is it to your speakers?
good luck.

Just did that, same result. Nothing muted except external amp gives the buzzing noise. I then mute the digital output jack and everything goes quiet.

I just have it connected to a receiver which powers two speakers. No microphones are hooked up. Works fine under WinXP and with my other computers.

Thanks.

You may need to add a module for sound to the kernel, passed a web site on it, but dont have the link. I am running FC3 and just used the Alsa drivers and it worked. Am using an AWE64.

Does anyone have any other suggestions? I'm still at a loss (for sound). Thanks!

wingedpig:
i have the same problem. sound worked perfect in FC1, but i have nothing here. i've messed around with alsamixer extensively, but nothing seems to have worked.
how exactly are you connecting to your stereo? i personally run an optical cable from my audigy faceplate right into my harman/kardon receiver. what i'm confused at in alsamixer is that a few channels WON'T turn on. they are:
"External Amplifier"
"Audity Analog/Digital Output Jack"
"IEC958 Optical Raw"
"Mic Boost (+20dB)"
"Tone"
i've tried all sorts of configurations of the other, working sliders: no dice. but i feel like the "Audigy Analog/Dig..." and the "IEC958..." sliders are the ones i want, and i don't understand why they aren't working in alsamixer...
anyone have ideas?
good luck all

yeah i'm looking this over... how are ALL of you connecting to your stereos? it just seems counterintuitive to me to mute "audigy analog/digital" OR the optical out when i'm using a digital, optical signal. and either way why are those channels listed but not controllable?
thanks all,
spencer

is there any alternative to alsa?

mine wont work at all.... and when i hit play sound, it adjust alsmamixer iteself. I have tried muting most things. there is so much crap in there that i know nothing about. I am using a standard audigy with 5.1 surround.

ok so:
i was messing around with my computer and realized that i hadn't tried any of the non-optical jacks. so i did. and they work, at least the 1/4" ones. but why doesn't the optical?

I recently installed FC3 and I am coming from red hat 9. I have SB live with some quality speakers, I messed around with alsamixer and I got sound now but the quality is terrible compared to what it was before. It also won't get near as loud as it used. I am at a lose.

Hey Brobzilla... that sounds weird!

go to a terminal, and type in 'kmix' or use 'alsamixer'

try playing around with the PCM. Sometimes of the PCM is too high, the sound quality becomes terrible...

Hoped that helped.

Zubin Hey Thanks soo much. I messed around with kmix and I got it working much better in mins.

b r0b-zilla

i have no sound either. i messed with alsamixer and kmix without luck. got ac97

Hey bjuhn,

Try opening up kmix, go to the 'Switches' tab and try unmute / mute each one there separately... I believe it actually the Analog/Digital one...

Make sure you have music playing so that when you adjust the right switch, you'll here music...

If you're gonna play an MP3, make sure that you have the mp3 plugin installed.

My system:
Linux *** 2.6.10-1.8_FC2 #1 Mon Jan 10 14:46:18 EST 2005 i686 i686 i386 GNU/Linux
Multimedia audio controller: Intel Corp. 82801DB (ICH4) AC'97 Audio Controller (rev 02)

I had same problem -- I did a couple of things, using alsamixer from a terminal:

1. I made sure PCM, PCM2, Master Volume were unmuted and had reasonable levels.
2. I muted all of the devices not present on my system, for example:
Headphone Jack Sense, Line Jack Sense
3. I then got sound, and unmuted above devices until sound disappeared again. What it boils down to is that for me at least Headphone Jack Sense, Line Jack Sense needed to be muted.

Now what I'd like to know, is where are these config settings stored? Someone switched my desktop from KDE to Gnome and thats how I re-lost my sound in the first place.
