Here are some details:
System: Intel Core 2 Duo E6600 Asus P5W DH Motherboard X-Fi eXtreme Music Intel HD audio onboard
Software: Advanced Linux Sound Architecture Driver Version 1.0.20. Compiled on May 16 2009 for kernel 2.6.28-11-generic (SMP).
Running Kubuntu 9.04, with default packages.
All major audio players tested and work fine. Aduiocious does not work with 24bit mode as reported before.
System is stable, no issues encountered yet!
Recording through the mic works flawlessly. Sound from speakers seem clear. Switching between intel HD onboard audio and xfi works fine, both enabled on the same system.
P.S I installed the file alsa-driver-unstable-snapshot.tar.gz now my alsa version is 1.0.20 instead of .18, does that cause major issues? I thought the package will only install the module snd-ctxfi, not the whole alsa! or is that not possible.
Let me know if you want me to run specific test.
Regards.
