[Issue] Debian Wheezy - No Sound, At All

I freakin’ give up.

I’ve spent the last TEN HOURS trying to get sound off this damn thing.

I have one of those Syba USB stereo adapters (http://www.newegg.com/Product/Product.aspx?Item=N82E16812186035)

‘sudo lsusb’ shows it as a C-Media Electronics, Inc.
–I assume that’s right

But no sound…nothing.

I’ve tried doing something with ALSA…I think. Apparently it (alsa-base/util) weren’t even installed. So I ‘apt-get’ got those.
–If it helps, I’ve included a ‘print out’ of the installed packages.
–Also, alsa-base.conf ‘options snd-usb-audio index =0’ (was =-2)

It shouldn’t be this hard, even for Linux, obviously I’m doing something wrong…but I have no idea what.

installed_packs.rtf (22 KB)

Which board? What kernel (uname -r)? What vid/pid (lsusb)?

Also, it would help to dump your full dmesg:

dmesg | pastebinit

(then send us the http link..)


Not only that, but what does lsmod have to say ? Is there a driver installed for it already ?

And here you go.

Sorry, about that. Google Groups asked for the topics and I picked there.

BeagleBone Black (with eMMC; A5 revision?; just got it 3 days ago)
Kernel: 3.8.13-bone26
OS: Debian Wheezy; apt-get update (and upgrade) have been run prior and after adding the additional hardware
sudo lsusb: http://paste.debian.net/47695/
-they cgynals are ASICminer USB Block Erupters; they work
-two (4 port) USB hubs daisy-chained; I’ve tried both top hub and bottom hub…same result


It appears to be working now…but on when logged into ‘root’.

It’s odd though, because neither the TI BeagleBone Black Analog Stereo or C-Media USB Audio Device show up when logged into my user account. Not sure why Linux would default the users to not having sound.
–All apt-get commands are done using ‘sudo’ to insure they work.


I may have found the problem. It appears accounts need to belong to the ‘audio group’…problem is /etc/passwd/ doesn’t have anything with “audio”. I now have access to audio.

…now to figure out why Google Music’s music doesn’t have any audio. Also, why VLC, too, doesn’t have any sound; regardless of the ‘output’ chosen.

That's weird..
default user should be in the audio group..

Using aplay --list-devices

try setting..



Figured it out. Apparently if you installed VLC first then PulseAudio. VLC has no idea how to ‘talk’. A simple uninstall/purge of VLC and reinstall seems to resolve this.

As for the User Account. I removed ‘debian’ since I’ll be running this Beagle 24/7. I didn’t want unauthorized WAN access. Still it seems odd that Linux wouldn’t auto-add new users to at least the ‘audio’ group, unless specifically told to do so with a command option (ie --no-snd) after the useradd (or was it adduser; I can’t remember) command.

I’ll forget about Google Music. Youtube audio will play, but man is it choppy. I would assume playing from Google Music would result in the same stuttering.
