Clicking from sound card

[Phil <phil@spiderweb.com.au>]

Hello everyone,

Thank you for reading this.

I've had limited success with digital modes, such as PSK31, because of a 
random clicking sound that's very noticeable. It almost sounds like a loose 
connection, but it's not. The sound card, and PSK31, both work perfectly 
under Microsoft's Windows.

I've tried two different Sound Blaster cards and both the OSS and Alsa 
drivers. The clicking sound is faster with the Alsa driver. The drivers are 
ES1371 and SND-ENS1371 respectively. I've disabled any services that I 
thought might be interrupting the sound system but without any noticeable 
effect.

The clicking can be heard behind system sounds as well (such as opening or 
closing a window). MP3 files play without any clicking at all.

I'm currently operating under Mandrake 9.2 and I had the same clicking under 
9.1 so perhaps it's more likely a hardware issue.

Has anyone else experienced this annoying problem or can anyone offer a 
suggestion for a cure?
