hmm... I guess you're right... My sound chip is Realtek ALC850 and I've checked and it turned out there is no hardware midi:( >> The second problem is related to Debian AMD64 only - the problem was >> not present on Debian i386 (do you use the Debian AMD64?). >> The sound driver can be used only by one app at a time (for example >> when I listen to music with xmms the KDE has no access to the sound >> device; or when KDE uses the sound device (through aRts) no other app >> has access to the sound device, etc).

But maby the app I ran in the console used OSS (it was skype ran via chroot). But as I wrote the problem is _only_ when I use Debian AMD64. I have also Debian i386 installed and the same apps when running under the i386 Debian they have no problems with sound.
