Sound is grainy when my graphics card is doing shit

[rabbitweed]

For example, when i play a music file in totem, with the visualisation thing going on, the sound will be grainy and shit.

I have nvidia-glx-new, which is correct for my graphics card.

really have no idea where to go from here, yes I googled, ideas?

But with aplay or ogg123 it works fine?

I don't have either of those, but it sounds fine in rhythmbox, and xine, and anything else that doesn't have visualisations.

It's not hardware, i could play an audio file with visualisations in ubuntu feisty (with totem), and mswindows 2000 (with windows media player).

Does this happen using vesa/nv?

[rabbitweed]

aha, it works fine with nv.

I'll see if I can't go back to nvidia-glx, as opposed to nvidia-glx-new.

Last time I tried shit like this i killed X...wish me luck

Try disabling Desktop Effects, or parts of it. You can install the package compizconfig-settings-manager to have a finer-grained configuration (and enable flashier plugins) -- go into that and experiment. A lot of the stuff in Compiz-Fusion is relatively unstable, and I suspect a lot got pushed into the default install just to have a shiny desktop.

I use fluxbox, and in gnome compiz is disabled (can't stand it myself).

I'm assuming you're on an integrated sound chip?

My guess is there's some sort of interference going on between your graphics card and your sound chip (I'm not an electronics nerd so I can't speculate further as I don't know what I'm talking about ) - using nv/vesa moves graphics processing to your CPU, leaving your graphics card to merely shove out a video signal to a monitor. Try checking it's plugged in completely, blow out all dust, etc. Also try googling for eliminating sound card interference, dunno if you'll find anything.

A solution would probably be to just buy/scrounge an old dedicated sound card. Old Creative ones are very good with Alsa, X-Fis are a waste of whatever you pay for them - the current drivers provided by Creative are x86_64 only and do no more than provide basic sound. This may change with the next release of alsa but don't hold your breath.

You clever bastard, that sounds like the problem!

My graphics card is integrated as well.

Possibly an IRQ conflict or some such shit.
