Realtek AC'97 problem under RedHat9, Fedora!! No sound input possible!!!

Dziri · 06-29-2005, 09:58 AM

Hello everyone,

I am encountering an audio problem and am in dire need of help, so any hints anyone could give me are most welcome. Here is the situation:
I have an integrated sound card on the NEC machine i'm currently working on. It's a realtek AC'97; I'm working under redhat9 and fedora core 3 and under both i have the same problem: microphone does not work, that is to say that the inline is misconfigured, if configured at all... This problem is pretty annoying in my case, since i'm supposed to be building a VoIP demo platform!!! You can imagine that VoIP without voice is... frustrating to say the least! When I try running softphones, the usual error I get is something like: "Audio device not found" or "Failed to Open audio device" or "audio device probably busy" and so on. I tried recording sound using the gnome sound recorder, but to no avail. Complete silence, and when I tried closing it it crashed, so I thought maybe it was bugged; I then installed audacity to make sure I do have a problem and, sure enough, the problem is there! No input, no voice, no sound!! please help, if you can!!

Here is the /sbin/lspci output, like advised:

Do you have redhat 9 or fedora core 1?

RedHat9

Erhhhh.....I have used Fedora Core3 for half year,the sound really annoyed me,Maybe the driver doesnt fit for your Audio chip,would u try some other distribution,or recompile the kernel, adding the thirdpart driver.

Dziri, I too have gone through the painfull experiance of using bonephone!

I did a project at University which was building a VoIP Call Center. Instead of writing the VoIP stuff ourselves, we used bonephone.

We had simmilar problems with audio (I was running RedHat 8 with same soundcard as you have). The Advanced Linux Sound Architecture (ALSA) software fixed all of these problems, and I highly recommend it.
See: http://www.alsa-project.org/
Once installed all sound playback and recording worked perfectly.

On another note, my supervisor from university is installing our software on a new machine, and he is having the same problem as yourself with multicasting:

Code:

LOCALHOST: 192.168.2.1
Message Bus configuration:
Address    : 224.255.222.239
Port       : 47001
TTL        : 0
HashKey    : Key using HMAC-MD5-96
EncryptKey : Key using NOENCR
CheckDigest: false
sendUnicast: false
ignoreSeq  : true
 
--> java.net.SocketException: No such device
null

Just wondering if you have had any luck finding a solution

Thanks,
Gerard
