[ubuntu] sound not working after upgrade to 9.04

[bhavikpatel]

Hi All,

I was successfully using ubuntu 8.10 till yesterday evening, and my mind gone bad and I decided to upgrade it to 9.04. After upgrade, everything was perfect, and sound was working perfectly. I watched a movie yesterday night, and I slept after that.

Now I wakeup today morning, and "bang"! The sound is not working in ubuntu!
I really like ubuntu for it's speed and effieciency, but the problem like this forces me to use Vista even though I hate it!!

Now coming to my problem, can anyone tell me what the heck is going on in my PC?

I have tried following steps mentioned in past threads in this forum, but nothing working.

Here's the output of some of the commands:

$ cat /proc/asound/modules
0 snd_hda_intel

$ cat /proc/asound/cards
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xf6480000 irq 21

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: CONEXANT Analog [CONEXANT Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: Conexant Digital [Conexant Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0

Please help me to solve this problem. I can give more info about my hardware, but you have to tell me which command I have to run, because I don't know the commands at the moment.

Thanks for the help.

Sorry man, lots of us are having the same problem. I've tried heaps of things and nothing seems to fix it. Lets hope Canonical fixes this very fast.

Me too; upgraded to 9.04, and no sound! Tried uninstalling/reinstalling
drivers, etc., no dice. This forced me to install RealPlayer11GOLD.exe
on windows XP, even though this installer requires an internet connection.
Normally, I don't allow windows onto the internet, because of the sneaky
aspects of Microsoft's design, so I had to install the nic driver to XP
long enough to do the install, then quickly uninstall the windows nic
driver, since windows is a virus-magnet. Ugh! I also hope they fix this
sound problem fast.--blurt.

No sound. HP DV7 1260us sound working perfectly in Kubuntu 8.10. After upgrade to Kubuntu 9.04 sound stopped working.

It also stopped working on my HP HDX9480EG Laptop since I updated Ubuntu

The model of my sound card is:

romana@romana-laptop:~$ cat /proc/asound/card0/codec#* | grep Codec Codec: SigmaTel STAC9271D

I tried to install the lates driver, but it does not work:

This actually seems to be working for the time being

sudo adduser <username> audio

Even though there was no audio group before.

Got the suggestion from here:

Hello.

I am following this branch because I've got almost same problems like everybody here, but almost is key word for me .

I have laptop HP DV7 1135nr.
Alsa used module snd-hda-intel
Sound works fine for me, except one thing I have built in microphone which does not works, I've noticed same problems on 8.10 in December (I was trying different versions, before I finally choose 8.4 like most working out the box). But now I am trying utilize all nice features from 9.04 and once I've update to 8.10 and everything works so far, I thought that probably I can successfully update to 9.04 but ... microphone not working so far, and "Volume control" don't remember my changes on "Recording" tabsheet. That seems very strange for me I don't wanna back to 8.04, but it looks like most stable and working system for my laptop

Thanks everybody who post different solutions here, I've tried everything from this branch but nothing work for me so far.

So ummm...what I said worked for me previously, no longer works for me. Any suggestions?
