I'm having sound issues as well, and this may help others though my problem
isn't fixed.
What I have: Sound Blaster Audigy 2 ZS Platinum Pro
Windows Vista Beta 2 32bit
Creative Labs Beta Drivers from November
Current Creative Labs Windows XP Drivers
Problem:
Input audio (from a microphone) is scratch and can't be listened to.
Audio Playback is half and half. Sometimes it's scratch and unlistenable,
and sometimes it's crystal clear. Through my headphones, it's always bad,
sometimes it's 50/50 with my speakers. If I open an MP3, it's scratchy as
hell. If I pause it and play again, it comes out clear. I can't determine
why, either way.
I was able to install the beta drivers. The current XP did error out on me
during the installation and even blue-screened on me, and when it rebooted it
found new hardware and bluescreened again. The third time I just hit cancel
on the install of the new device, and the audio works (But with no change in
the above symptoms.)
My benefit is that I can play battlefield 2 with audio and listen to MP3's
if I pause and replay. Hope I could shed some light, but if not at least your
not alone and there's another with problems added to the list.
