I have been using a Dell SMB dual PII/300 box with cs4232 playing my MP3s in a loop 24x7 for nearly a year without any glitches. I have tried it with 2.2 kernels and 2.4.0. The only problem I have had with the box and sound driver was that I had to set the PCI quirks flag to 1 (thanks to Alan for pointing me to it) to keep it from crashing when playing sound and accessing the floppy (this got QUITE embarassing when I was doing some custom work for some high-level folks a while back). However, I have one beef with the driver. Each time it starts a cut, I get a loud pop from the speaker. This appears to be a startup transient and is not present on my other sound card in the box, a SoundBlaster Vibra 16. This pop happens on ANY play application, playing ANY file (esdplay, play[sox], vplay, xmms, etc.). Cheers, -- Wade Hampton
