Are the ALSA packages installed?

Can you get sound from the command line, e.g.:

aplay /usr/share/sounds/alsa/Front_Center.wav

Note: the wav files might get installed to a different dir on your box.

have you tried alsamixer to adjust the volume levels?

have you tried the alsaunmute command?

is there a physical volume knob on your laptop/speakers?

Which alsa packages? Thanks

$ aplay /usr/share/sounds/alsa/Front_Center.wav

Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

But no sound.

have you tried alsamixer to adjust the volume levels?

Yes. All at max level

have you tried the alsaunmute command?

No. How to recheck it?

is there a physical volume knob on your laptop/speakers?

No. This is a dualboot system. Fedora 17 also is running on this HDD. Sound works without problem.

Which alsa packages?

if the aplay command worked without spewing errors to the console, then you've got them installed.

have you tried the alsaunmute command?

No. How to recheck it?

just run that command by itself in the terminal, possibly with sudo, e.g.:

sudo alsaunmute

Also check if your user is added to

$ groups harry
harry : harry lp dialout cdrom floppy sudo audio dip video plugdev users netdev

as you can see. I am added to audio group.

Happen to find a solution to this, satimis? I have the same hardware and have been experiencing the same problems. Haven't had any luck with anything I've read elsewhere.

Hello and welcome!

Have you tried applying system updates to your Ubuntu box, in order to ensure that you have the latest kernel and ALSA packages installed?

Have you confirmed all the things Satimis did in his last post?

[dukemockingbird]

Thanks, atreyu. I did apply all updates. to include the latest kernel and alsa packages. Also confirmed I did everything satimis did. Did not solve the problem, but...

When switching to a command line via Ctrl-Alt-F1 (because the system was freezing up now and then), I noticed the the system spewing out the following error repeatedly: "3:3:4: cannot set freq 48000 to ep 0x86"

Searching on this error immediately revealed that this was caused by my Logitech webcam. In this case, the C310. Sounds like some of the Logitech webcams don't work well with some of the newer kernels, based on the quick search I did.

Shutdown, unplugged the cam, and started up. 12.04 works without problem! No lag before the cursor appears on the login screen, sound works, no more system freezes. And if I plug in the cam after I'm logged it, the system continues to work correctly.

Hey, that is good!

That seems a bit bizarre. Perhaps there is a race condition going on. Consider filing a bug report to help out Ubuntu.
