Audio drivers are crashing

[biosftw]

hey I got a problem:

My audio card is crashing from time to time with the following message:
The audio playback device "HDA Intel (AD198x Analog)" does not work.
Falling back to.

The crash seems to be randomly and I can fix the problem with a reboot

any other solutions?

Aplay -l:

The audio playback device "HDA Intel (AD198x Analog)" does not work.
Falling back to.

I get that crash message on my desktop Kubuntu system every time I boot it. It is a phonon message. In my case, it is errrr LYING! There's no actual crash of anything.

So, you might want to examine the possibility that there's not actually problem with your audio. Your "aplay -l" output looks reasonable. Can you play music?

Re: Audio drivers are crashing

Just got the crash again:
Well I can play a stream via the plasma-widget: Simplestream
But I dont hear anything via amarok and flashplayers like youtube

Re: Audio drivers are crashing

biosftw i had the same problem when i was running jaunty but when i updated to karmic the problem was solved. I run a Sony Vaio laptop.

Would be nice to show us your audio devices by: lspci -v (copy paste here only your audio devices)

I read in alsa manual that modules intelx08 and intelx08m support up to the ICH7 family audio controller. So you must use the snd-hda-intel for ICH8 and above if im not wrong.

It is my post that i had a problem with sound when i updated to karmic but my problem was due to kernel reasons.

Nevertheless, at my post look at dibl's second post. There, he has added two very useful links for troubleshooting your audio problems. Check carefully both links.

Personally i would suggest upgrading to karmic. I don't know what audio devices your laptop/pc is using but I think it offers a better driver support. It did for me.
The final choice is yours.

I get something similar, on booting phonon reports that Pulseaudio is not working falling back to HDA Intel.....which is interesting because pulseaudio doesn't exist on my system yet it still appears as an audio output in multimedia settings.

In 9.10 I get audio from most media players but not in any browser (Opera/Firefox/Konqueror) whereas everything worked in 9.04.

I am getting the exact same error when KDE starts up for me as well. It tells me pulseaudio does not work and it is falling back to HDA Intel. Pulseaudio is not installed, and in the device list Pulseaudio is listed, but at the bottom of the device list.

Also as above, audio works for some media players, but not in any browser. Audio worked fine in 9.04. This is a 3 yr old Dell Precision M90 laptop with a completely fresh install.

Kubuntu is feeling like a 2 steps forward, 1 step back installation...

This appears to be a very similar problem as in this thread:

I assume you have demoted Pulseaudio to the bottom of the list for every category?

I have now discovered the lack of sound in browsers; in KMix enable the PCM channel and set its volume level to 100%.
