I had sound working with R5D1, but after upgrading to R5E50 I don't have any sound. I tried alsaconf and making sure no sources were muted with alsamixer. That's about the extent of my knowledge. Are there any other tests I could try? Is it possible it's somehow related to udev changes?

Don't think that's my issue, didn't have an /etc/asound.conf file in R5D1, but it was worth a shot.

One thing I notice is that my audio device in setup is /dev/dsp0, mixer device is /dev/mixer (mixer controls: pcm).
When I look in /dev, I don't have either device. There is a /dev/dsp, but no /dev/mixer. A soft link of /dev/dsp0 to /dev/dsp didn't seem to help.

You may need to "modprobe" the appropriate driver module for your sound card... What does this show on your machine?

Yes, that's it I don't have any audio devices!
ls -l /dev/ | grep audio
crw-rw---- 1 root audio 10, 135 Dec 27 19:55 rtc
lsmod | grep snd

Ran alsaconf, changed /dev/dsp0 to /dev/dsp in setup, audio is working again. I think my root problem was the saved audio device name from R5D1 setup (/dev/dsp0).
Thanks for the help.

I am having the same type of problem. I have changed my audio settings to /dev/dsp from /dev/dsp0. Ran alsaconf, selected my audio card, alsaconf went to load the drivers and threw up:
Code: Fatal: Error inserting snd_had_intel (lib/modules/2.6.18-chw-13/updates/alsa/pci/had/snd-hda-intel.ko): Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error running install command for snd_hda_intel
Setting Default volumes...
amixer: Mixer attach default error: No such device.
Code: ls -l /dev/ | grep audio
crw-rw---- 1 root audio 10, 135 Dec 30 10:50 rtc
Code: lsmod | grep snd
snd_hda_codec 159232 0
snd_pcm_oss 42912 0
snd_mixer_oss 18176 1 snd_pcm_oss
snd_pcm 69380 2 snd_hda_codec,snd_pcm_oss
snd_timer 22404 1 snd_pcm
snd 47588 5 snd_hda_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore 11360 1 snd
snd_page_alloc 11784 1 snd_pcm
Any suggestions. When I upgraded to R5E50, at first the sound worked, now nothing, and I cant access alsamixer.
Thanks in advance. _________________ -Roseville, Michigan USA LinHES R8: FE/BE, FE (x2)

I've got the same problem with the E50 frontend. I'm using an IBM thinkpad T43, and when I load the KM frontend there are no sound devices in /dev.
Sound in R5D1 worked without additional setup, right from boot.

more info (sorry, I'm using the same laptop to post as I am to test):
After boot of E50, no sound, no sound devices, 'aumix' command fails. Far fewer files in /dev under E50 than under R5D1. Alsaconf detects the Intel 8xx soundcard, but fails, not finding the device files.
I mknod the various audio *0 devices, and then soft links (like mixer -> mixer0). Alsaconf works better, but still has a few hardware not found errors.
Mixer now will run, in that I can adjust levels of audio in/out devices. However, still no sound.

From the Main menu in the GUI it's: utilities/setup -> setup -> general -> 3rd screen
