Summary: Mp3+ crackles when on alsa, not when on oss emulation
Description:
this shell-cut-and-paste wil ilustrate my problem:
At first when I plug my mp3+ in, it crackles. It is not scraping or
static, it is a distinct pop in the sound about 2-3 times/sec not
rythmical. The card shows up in alsamixer -c1, and everything about
controling it works. Then, without plugging my card in or out, I do this:
[root@localhost hhg]# rmmod snd_usb_audio
[root@localhost hhg]# modprobe audio
[root@localhost hhg]# alsamixer -c1
alsamixer: function snd_ctl_open failed for hw:1: No such file or
directory
I also have a boult-in intel-8x0-card working fine with alsa. But now the
mp3+card works great. Using oss-emulated mixer the card can also be
controled. I have to use oss-output, though, as the card no longer is
registrered by alsa.
even if I do
[root@localhost hhg]# modprobe snd-usb-audio
alsamixer -c1 fails and the card stil works as an oss-card.

Sounds like you are missing the ALSA device nodes in /dev. Did you run
the snddevices script?

After reading a previous bug, I discovered that when I plug my mp3+
directly into my pc and not via my usb2.0-hub (sweex hub) the crackling
goes away when on alsa-driver.
This is very strange. How can alsa not send good data through the hub when
the oss-emulator (audio) can do it just fine?

I think this is user error. The "audio" module is not related to OSS
emulation, it's the real OSS driver, so of course when you remove
snd-usb-audio and modprobe audio then alsamixer will not work.
