Hi Mlt,
Could you please describe (or add a wave file) in what way the audio is bad? High background noise? Digital clip? Choppy?

Hi,

It sounds as if it is being played on a radio with a broken speaker - notes are blurred and distorted, and there is almost white noise. also oddly, there is a time signature problem, a track will speed up and slow down, and it seems that this depends on other processes that are being carried out. I have tried headphones and it is as bad on them as the internal speakers on my laptop. Previously on 10.10 the sound had been fine.

Details of my sound device:

Hmm, this is nothing I've heard about before and I don't really know how to attack the problem, but we should try to figure out where in the chain it appears.
You don't have too high volume somewhere causing digital distortion?
Is the problem present is you try another sound card (e g USB headphones if you have any)?

If you run
pasuspender -- speaker-test -c 2 -t sine -D plughw:0

...is the sound still broken?

I tried the command below and there is a nice clean tone broken up intermittently by interference like noise about 1/4 - 1/2 a second long.

I tried all the volume controls and they didn't change distortion.

I have just tried this with the latest SUSE live CD and that also has distortion.

Ok; I'm out of ideas at the moment, and I'm not excluding a hardware fault on your computer, but if you can figure out more information about how or when it appears, or what causes it to appear, that is likely to be helpful in tracing this bug down.

I'll double check the hardware and get back to you.

Having spent the day fiddling, an update on this.

This is not a hardware fault as an install of 10.10 works fine (with gnome and kde)

I updated to 11.04 and the problem came back in KDE, I'm not able to log into unity or gnome so I can't test whether it works outside of KDE!

I tried xine and gstreamer but had the problem in both.

I updated to 11.04 and the problem came back in KDE, however in Unity and lubuntu the sound is fine. I tried xine and gstreamer but have had the problem in both.

Ok, thanks for the comments. If you're up for more time-consuming tasks, you could try bisecting - first thing to try if so would be to start off with Maverick, verify that it works fine, then install this https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules, reboot, and see if the problem has reappeared?

Have the same problem here. This happened on both my two T60 Notebooks. It started out after updating them to Natty. One was running Lucid, the other one a Maverick before.

Have to validate, but I think dropping pulse-audio did fix it. Will follow up when I know more.

Simon Huerlimann (huerlisi) wrote :

The following did help:

sudo apt-get remove pulseaudio pulseaudio-utils

I'm using Kubuntu/KDE. I've been asked if I'd like to remove a few sound devices right after the login. The following message was in the Notification log:

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

Thanks for the suggestion -it certainly helps and reduces the occurences of distortion.

Having said that, launching REkonq to write this did cause some problems, so there seems to be a resources issue somehow?

Mlt (mlt) wrote :

further weirdness - if I switch off desktop effects, the sound is fine. Are these using resources in a different way than previously and is this intended?

eaglegranlin (eaglegranlin) wrote :

I have the very same problem on my Inspiron 6400, for some reason when i'm having some graphical charge i get that annoying distortion, even though my fps do not drop, as Mlt says when i switch off desktop effects the sound fixes

David Henningsson (diwic) wrote :

@Mlt, if you remove pulseaudio, you also remove the "mixing" functionality, that allows more than one application to have sound at a specific point in time.

Mlt (mlt) wrote :

@DavidH - true, but the problems with graphics, not sound and the problem is there with pulseaudio as well.

David Henningsson (diwic) wrote :

Aha, I thought you meant "system event sounds", but you actually mean switching from compiz to metacity?

Sorry, it only happens in KDE - gnome/unity, etc. is unaffected

This seems to have been solved know since I updated to KDE SC 4.6.3. There is no distortion, pulseaudio or not.

Thanks

Is there anyway of pushing this to KDE as it clear that this is where the problem is?
