ubuntu No sound after Update

Well let me begin by saying thank you to everyone here in the forums as I have always been able to find the solution in the previous posts. However, now I am stumped.



This morning I was notified that updates were available, I reviewed the updates and noticed that many were to PulseAudio. I didn't think anything about it and went ahead and applied the updates. Upon completion it called for a reboot, which I did and now no sound. I checked all the standard things, lsmod shows the driver is loaded, aplay -l shows the card as available, volume is set to 100%, but still nothing. I have no idea where to turn on this one being it was working before the update.



Did anyone else get these updates today? Did you have problems as well?



Thanks for you help!

I have the same problem. My system has a built in Intel sound card and an added Creative labs Audigy 2 sound card. When I originally installed Kubuntu, I had a similar problem and the solution turned out to be installing "asoundconf-gtk", which allowed me to set the Audigy 2 as the default sound card. This time, no luck. I have checked and volume on all the PCM settings is on 100%

THat is the same exact setup that I have. Intel on-board (disabled in bios) and snd_via82xx is blacklisted, and nothing. Dead silence. Not sure where to turn or what to do next.

I did the same update and my sound is gone - My card is a Audigy 2 ZS and I have never had sound problems before. Something introduced in the last update had killed sound for this card. The kernel was updated as well in the latest series of updates. I will boot into the older kernel and let you know if I have sound.
I reverted to the previous kernel and my sound is back. The problem is with the kernel upgrade not the pulse audio upgrade.
That works for me to. So kernel 2.6.27-11 has sound issues.
Same thing. Rebooted with kernel 2.6.27-9 and my sound is back.



Thanks rigelstar.

I have the same card and the same problem. Guess I'll boot from the earlier kernel.
Atm I'm not inclined to upgrade the kernel (have audigy 2 Zs) though curiosity will probably get the better of me.



I noticed one line in the upgrade


Quote:







ALSA: emu10k1 - Add more invert_shared_spdif flag to Audigy models


Possibly the output has been switched to spdif or the Audigy Analog/Digitial output Jack has switched. (On my card it needs to be on for sound.

It can be found in the full alsamixer as Audigy A (00 is on) or in 'switches' (d. left click on speaker icon -> preferences and add the switch, then in 'switches' check or uncheck depending on audigy card





To get full alsamixer if not available

to find card #, usually 0


Code:

cat /proc/asound/cards


Code:

alsamixer -c 0

After update this morning I had same problem. I used the directions on the following thread and upon reboot sound was restored. Don't know if it will be your solution also, it worked here though.

after this sound in rythmbox was scratchy. So I did this:
