What steps will reproduce the problem?
1. Open a sound file of your choice in audacity
2.
3.

What is the expected output? What happens instead?

What version of the driver are you using? On what operating system? What
version of the operationg system are you using (32 or 64 bit)?

What ports of the soundcard are affected by the bug (e.g. SPDIF, Mic-In)?

Please provide any additional information below.

Ah crap, I pressed enter for a newline and it posted this before I could even 
write
it and I see no option to undo this mistake. I'll continue my report here.

Title: Slow/low-pitch playback for 22khz wav files and in other instances

Ports Affected: Main stereo analogue out

Reproduction:
1. Open a sound file of your choice in Audacity
2. Set project frequency to 22khz
3. Play the file

As for the "other instances", I've also noticed that while playing Team 
Fortress 2,
some custom sounds that I have installed suffer similarly. Some are 22khz files 
play
fine while others don't and it even seems to happen to some 44khz files. None 
of the
issues seem to depend on bits-per-sample nor the number of channels. I have no
further information on how to reproduce, but if you want examples of files that 
work
and files that don't, please ask.

Once again, sorry for messing up the initial submission.

Things are getting really weird now. Right after I wrote that comment, I've 
stopped
being able to reproduce the problem. I shall continue my investigation of this

Sorry, I forgot to mention that I'm using 1.2.0 on 32-bit XP SP3

this sounds odd - could you please disable the 88.1 and 96 kHz sample rates in 
the 
control panel applet and then try to reproduce the problem?

I switched to my onboard audio and got the same issues in Team Fortress 2, so I 
guess
that could be a Source engine bug, but I can't find anyone else who has or had 
this
problem.

I've still been unable to reproduce in Audacity and disabling 88.2 and 96khz 
seems to
have had no effect on anything. On another note, if I uncheck "Enable S/PDIF 
output"
in the panel applet, I get no sound at all, despite using analogue ports.

I've also tried a different c-media card and everything is the same.

The "enable s/pdif output" option is indeed somewhat misleading for some 
hardware 
revisions - the switch disables the DAC for these. I've simply adopted the 
notation 
from the specifications of the hardware.

The issue with tf2 sounds like there's some error in the mixing process - 
presumably, all the sounds are mixed dynamically during runtime into a single 
stream 
which is being played constantly. The driver has no effect on that. My idea was 
that 
on some systems, the highest sampling rate is chosen for the resulting stream, 
and 
some 8738 revisions handle 88.1kHz/96kHz improperly. But since the same bug 
appears 
also when using your onboard sound adapter, I'd guess that it's caused by 
userspace 
applications, too.
