RE: [linrad] Sound: Recording overflow

[Kohjin Yamada <jr1ede@xxxxxxxxxxxxxxx>]

Hi folks,

I opened up my RX2500 yesterday, what a surprise!
Seeing many pot cores and parts, I shut my hat off for Leif!
My very first fire-up was successful.

A console switching problem depends on the video card in use.
Matrox Millennium G400 causes the problem while nVIDIA GeForce2
and ATI Radeon AGP don't.

An audio overflows etc also are caused by the system's (kernel's)
other job, cron etc meant depends on CPU load.

A sound board selection is also important as my Turtle Beach Santa Cruz
causes many unknown problems and crashes many times.
Replacing by Delta 44 and/or Sound Blaster PCI128, all problems were
solved and I have never met any crashes since then.
My system is Red Hat 7.3 w/OSS 500MHz Pentium III 384MB/Ram.
By the way, RHL 8.0 is impressive though it eats CPU load a lot.
I ended up resuming back to 7.3 :-(

Share and Enjoy!
