Sound Playback fails to initailize

[GoogleCodeExporter]

What soundcard to you have (make, model, chip)?
Azurewave CMI-8738

What steps will reproduce the problem?
1. Boot Windows 7 or Vista (I'm dual booting off two disks) and attempt to
play any sound from any source...
2.
3.

What is the expected output? What happens instead?
The expected result is playback, but instead there's silence.
If I open a directsound stream shortly afterwards then both streams play,
until they're both closed again. The problem occurs again shortly after the
streams are closed.

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)?
1.2.3 - updated this morning, windows 7 (7100) 32-bit, vista SP1 embedded
32-bit

What ports of the soundcard are affected by the bug (e.g. SPDIF, Mic-In)?
All outputs, regardless of number of channels or configuration / redirection

Please provide any additional information below.

Windows Vista: that's probably caused by a bug in Windows: if you install the 
WaveRT version of the non-
WaveRT version and vice versa, the information defining the sound interface in 
the registry is messed up so 
that it doesn't work. Delete the corresponding item from the device manager, 
scan for new hardware and 
repeat that process until no drivers are found. Then reboot and install the 
driver of your choice.

Windows 7: Driver signing might be required even for the 32 bit version. A nice 
user has posted a short set of 
instructions on the UserComments page on how to test-sign it.

I've followed your instructions, but I'm still experiencing the same problems...
Another random thing I've noticed is that it seems to rectify itself if I change
output channels to from 5.1 to Quad or Stereo, but after a few stream open\close
orperations it does the same thing again, and subsequently changing output 
settings
doesn't have any effect.

This seems to be odd. I'd like you to answer a few questions to help me to get 
an idea about the bug:
What kind of player software do you use ? 
Do you use the analog or the digital ports of the soundcard?
What's your configuration in the Vista's "Sound" panel?

I'd also like to ask you to eliminate a hardware error by booting from a Linux 
livecd or by using the vendor's 
driver.

I'm using GOM player for video (www.gomlab.com/), and WinAMP for audio, as well 
as my
own apps (I'm a developer) utilising both waveout and directsound, and the 
problem
occurs in all of them, including WMP.

I'm using the analogue outputs, and Vista/Windows7's config is set to 5.1 with 
full
range all round. Windows panel seems to override your applet tho because if I 
change
the settings in your applet, when I click test they revert, and after an OK 
they're
back to Windows settings.

From the hardware side the card seems to be okay, it works fine in Ubuntu 9.10 
and in
Windows XP with CMI's drivers.

PS: WinAMP hangs when the output fails and all Windows sound stops as well.
Attempting to play Windows "Test" sounds fails, and you applet produces a 
message
saying it completed sucessfully, but there's no output.

In Vista and 7, changing the speaker configuration isn't possible anymore from 
a user mode app because 
the DS interface for that has been deprecated. The functionality for that in 
the applet is therefore non-
working.

I'll try to reproduce the error later this evening.

And I failed - it works flawlessly on my machine.

Please try the debug version here:

Before installing and during usage, run DebugView with kernel capture enabled. 
I 
need the debug log then to hopefully get a clue on what might go wrong.
