Clicking Crystal

Clicking Crystal

[Bungle]

Hi.
I have a Dell pc with on-board sound card in the form of Crystal CS4236 chips. I get a 
clicking noise at the beginning of sounds. Not allways - only if there is a period of silence 
first. For instance, if I am playing an MP3 and I do something in X that generates a sound 
event, the sound is hear fine with no clicking. But if there is no sound playing and a new 
sound is played, you get a click whose volume is proportionsal to the amount of time it's 
been silent for - ie longer silence gives a louder click.

If it was an analogue device, I would suspect a faulty decoupling capacitor, causing DC to 
build up on the output. But it's digital and only happens in Linux (not Windoze). This implies 
it is a driver thing.

Does anyone know a fix for this?

    I know a bug involved with latest drivers, which kernel do you use,
    and can you fetch the line where your soundcard is recognised
    with dmsg ?

Christoph,

I have had this problem with my cs4232 forever.
Is this something you plan on addressing in your
current wave of sound driver cleanup?

Thanks!

No. The cs4232 driver is only a wrapper around the ad1848/mss driver.
I did not change anything on the behavior off this driver. I have neither
a cs423x nor an ad1848 to verify this.

Kernel is 2.2.12-20
It is a not particularly modified RH6.1 install. I haven't messed around with the sound config 
(although it is possible that I should, but I can't find anything that looks like it will make a 
difference)

dmsg? What's that? I can't find that anywhere on the system. How do I use it (if I can get 
it)?

We are pleased to announce that after much pre and post y2k testing we have survived the 2000 rollover problem that everybody was expecting to have. We hope that we have tested all systems to death, but there may still be problems lurking in the bowels of our software. Be assured that any glitches that surface will be dealt with immediately.

In the meantime may we take this opportunity to wish you a prosperous 1900.

it's "dmesg", just execute it at the command line.
