Advanced Linux Sound Architecture Driver Version 0.9.0rc6.

Linux:
Linux version 2.4.19-k7 (herbert@gondolin) (gcc version 2.95.4

1. I'm suffering from my Extigy's 'click's.
Whenever I play any MP3s or WAVs in XMMS(both crossfade plugin using oss output and
oss plugin)/mpg123(oss output)/mpg321(oss output, alsa0.9 output) at 44.1KHz output
with usb-audio driver, I can notice continuous clicks.
In another 44.1KHz tests with Win2k, no clicks at all. At least, my Extigy H/W has no
problem.
Mysteriously, at 48KHz output(force conversion by crossfade plugin) in XMMS, there is
no click.
In summary,
44.1KHz with ALSA driver through OSS interface/ALSA0.9 interface: continuous clicks
(almost 2 clicks per second)
48KHz with ALSA driver through OSS interface: no clicks
44.1KHZ in Win2k: no clicks
2. Starting or stopping sound file play makes 'pop'.
I didn't heard it at all when I used Trident 4dwave NX.
3. An another thing. I can't use amixer/alsamixer. (still 'divide by zero' error,
invalid argument error) But the program using /dev/mixer works. (Although it worked,
there is a bug. Sometimes, master output level increased to 100% suddenly, making my
ears surprised!)
I could make many segfaults but they didn't make the system crashed.
Here is the error messages:
"""
$ amixer
Segmentation fault
$ alsamixer
alsamixer: function snd_mixer_load failed: Invalid argument
$ alsamixer
Segmentation fault
