Re: more than 16 bit audio

Thanks, vitamin!

Using "wine regedit", I was able to add the following registry keys to 
enable 32-bit, 96 kHz audio capture and playback (~/.wine/user.reg):

   [Software\\Wine\\Alsa Driver] 1300973815
   "AutoScanCards"="no"
   "AutoScanDevices"="yes"
   "DeviceCount"="1"
   "DeviceCTL1"="default"
   "DevicePCM1"="default"
   "UseDirectHW"="yes"

   [Software\\Wine\\DirectSound] 1300976391
   "DefaultBitsPerSample"="32"
   "DefaultSampleRate"="96000"
   "HardwareAcceleration"="Full"

   [Software\\Wine\\Drivers] 1300939175
   "Audio"="alsa"

In WINE 1.3.15, this allows me to play and record at 32-bit and 48kHz.  I 
can also record at 32-bit and 96kHz; however, the 96kHz playback is very 
distorted.

Curiously, the files I record in WINE (using Adobe Audition 3.0) play just 
fine using Audacity on the same Linux host.  But, playback within WINE is 
the problem.  Adjusting the buffer size in .asoundrc affects the distortion, 
but I've not been able to fix the problem.

Any suggestions?  Or, should I file this as a bug for dsound in wine?

Thanks!

FWIW, here's my current .asoundrc file:

   # Useful so that all settings can be changed to a different card here.
