Help!

Alright, I've read through all the posts that came up when I did a search and none of them have helped me! When I first installed FC3 on this laptop (IBM Thinkpad t42) everything worked like a dream! Even the wireless card was found (it didn't load properly, but it was found and that was more than I was expecting)! A couple of days ago I noticed that I no longer had sound! I came and did a search and read through maybe half a dozen threads and tried all of their suggestions to no avail.

I've tried checking the volume lvls with alsamixer, aumix and playing a sound file with aplay (all it did was say the sound played but no sound came out). I'm using Gnome, KDE isn't installed. I've downloaded all of the updates available.

Here is the output of lspci and cat /etc/modprobe.conf:

All help is greatly appreciated!!

Just a hunch, but did you try alsaconf by any chance? Did you follow the instructions on www.alsa-project.org, including downloading the drivers, libraries and utilities?

Sorry if I'm stating the obvious, it's all I could think of.

Cheers

Yes, I did run alsaconf and still the same thing.

I bet it's something simple that I'm missing.

I really don't want to have to reinstall FC3. Even on a T1 downloading all of those updates is a major pain! =/

Did you remember to set the permissions for the audio components properly?

eg. chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi

Cheers

Ovalteen

I was always under the impression that /dev/dsp was part of OSS and didn't effect ALSA. However, I tried the changes and still no go.

You are correct. My bad.

Are there devices in the /dev/snd folder?

Are you sure that the volume levels are unmuted? Even if you turned up the volume they might still be muted. You could try:
amixer set -c 1 Master 70 unmute
amixer set -c 1 PCM 70 unmute
amixer set -c 1 CD 70 unmute

I found this page pretty handy when I was setting up:
http://www.alsa-project.org/~valenty...i-HOWTO-7.html

EDIT - Also, what does it say in Gnome under Applications>Desktop Preferences>Advanced>Multimedia Systems Selector? Do you have a choice of ALSA and others, or just "Custom"? Excuse me if I've got the wrong menu, I hardly ever use Gnome. If ALSA shows up, then it's probably installed OK, you just need to tweak the volume settings of something. If not, then I imagine it's a bigger problem.

Cheers

Ovalteen

Yes, there is a /dev/snd directory. I set the permissions to 666 on everything in there and still no go. I've gone through that page and nothing there helped.

Anyone else have any ideas?

Alright,

I checked that menu. It had artsD, ESD, ALSA, OSS and Custom as options.

Everything except for ESD reported an error "Failed to construct test pipeline for ______"

*EDIT*
The program it was trying to run was "alsasink." I couldn't find that anywhere so I decided to reinstall all of the ALSA software just to be on the safe side. Well, it still didn't find it.

Anyone?

Pardon the *bump*!

Alright, got an update.

After spending all weekend trying to figure this mess out, I come in to work this morning and just reinstall FC3. The laptop boots up and not only does sound work, but I discover that the volume control buttons on the laptop ACTUALLY work! So, I start yum and let it run for the whole 3 hours it takes. Reboot and what do I find? Yep, you guessed it... No sound. Alright, so I get an epiphany. Maybe it's the new kernel. So I configure grub to use an older kernel and whabam! That's it. Sound now works.

So, the next question is why?

By latest kernel, I mean 2.6.10-1.770_FC3.

Anyone have an idea?

Thanks!
Brandon

Probably not what you're looking for, but my sound went screwy recently after changing to ALSA (from an oss driver). I found that it wasn't set to load on any init level. In my case, I found this by '/sbin/chkconfig --list alsa' and '/sbin/chkconfig --list sound'. I forget which is which, but I think it was alsa that showed off for all levels. I corrected by issuing '/sbin/chkconfig --add alsa'.

Don't know if any of this will even apply to what you're doing. I'm still a newb and on a different distro, but maybe something will help.

Same problem, its a kernal issue, workaround is to mute the Headphone Jack Sense option in the volume controls. Seems crazy, but it worked for me on a very similar configuration.

brandor--

I have experienced the same exact problem when i upgraded to the 2.6.10-1.770_FC3 kernel! When I attempt to use the volume control in Gnome, I get an error message that "Sorry, no mixer elements and/or devices found". Everything worked fine before. At least your post affirms for me that I am not imagining things!

Any advice anyone? This has got to be affecting others, too.

mconnor you are a genius! I spent an entire afternoon trying to get back sound in my IBM T42.

After muting Headphone Jack Sense *and* Line Jack Sense, sound is back! I had to register a user name to confirm this and thank you!

I am using 2.4.26-1-386 kernel though.

hey i am newbies too and i too have similar problem.

i have intel 815 board and pIII cpu and sound card is built in one the card is detected and working fine with rh9 but when i installed fc3 my sound card is not detected.;

same is the problem with other intel 845gebv2 board with soundcard built in .

pls any one help me or i have to reinstall the rh9.

i am thinking of changing the kernel back to rh9 ie. 2.4.18 one.
please suggest if it will work or not. also i think changing my kernel i may get my motorola sm56 modem work.

thanks
