Hi there,

I use Kernel 2.4.3 with an alsa-driver 0.5.9d,
alsa-lib 0.5.9 and alsa-utils 0.5.9b.
The soundcard I use is an FM801.

The sound playing works without any problems. But
if i stop playing the sound, i hear a shrill high
frequency sound which does not stop as long as i
start playing sound again.

Can so help me?

thanx
Tobias

Not familiar with that soundcard, but the first thing to check is mixer
settings, especially for microphone if you have one (feedback).

it is everything muted but the PCM and the
Master channels...

so i do not think it is the mixer setting.

thank you
