Same problem here.
Brand new Dell XPS 8110 (Intel Core i7-860 @ 2.8 GHz; 8 GB RAM; ATI Radeon
HD 5770; THX TruStudio; Bose 2.0 Companion speakers) running Win 7 Ult (64)
(fully patched; drivers and BIOS updated).
Audio generally works fine for Windows sounds (I think - under "default"
sound scheme), mp3/video, some of my 3rd-party apps, etc.
However, there are some notable bugs:
1) the OEM McAfee Security Center audio "alerts" (for: new updates
available, update installation complete, programs are up to date, scan
complete) do NOT play, even though the appropriate box is selected in the
McAfee configuration. I might not have even noticed, were I not already
running OEM McAfee in the EXACT SAME versions on my Vista Ultimate SP2
(32-bit) box. Other users at the McAfee forums report "no sound" with Win 7
(64), as well; others hadn't noticed, b/c they don't have the audio alert
function selected, or are new to McAfee, etc.
2) when configuring a couple of 3rd-party programs (Mailwasher Pro and
MSGTAG Status) in control panel > hardware & sound > sound > sounds to select
the sound for "new mail" and "read notifications" respectively, the WAV files
selected from among those stored in a folder on my computer do NOT work. The
EXACT same WAV files work fine in these same applications on BOTH my Vista
(32) (desktop) AND my Win 7 Pro (32) (laptop). Moreover, when I browse
through my entire collection of wav files, only 1 or 2 of them work when
selected to play in these applications. And ALL of the stored wav files play
fine from WMP and MediaMonkey. So, they are not "corrupted". They just
don't play within the Win 7 (64) OS itself. A similar problem occurs with
Thunderbird 3.0.1 -- although I have 1 of my own wav files selected for "new
mail", it plays the Windows default sound, instead. Again, my "custom" sound
works fine in TB on both other computers.
Troubleshooting thus far (all to no avail):
A. Ran the Windows audio troubleshooter - no problems detected
B. Verified that BIOS and all drivers are up to date - they are
C. Downloaded some new wav files, tested them for playback in WMP (work
fine) and tried them in both applications - no joy
D. Checked the Dell Support Center alerts for "sound problems with Win 7"
and ran all their steps - no problems, no resolution
E. Contacted Dell TS - they confirmed that "Win 7 (64) has problems playing
"old" wav files" & they get lots of calls on this!!!
F. Google search turns up numerous threads at MS forums and elsewhere about
this problem.
At least for me, the issue seems isolated to Win 7 ***64***, since the exact
same programs run fine with the exact same settings on my Win 7 (32) laptop
and/or my Win Vista (32) desktop.
This appears to be a SIGNIFICANT, increasingly common bug in Win 7 (64).
