             Bug #: 33722
           Summary: Stereo IMA ADPCM encoding in WINE produces loud static
                    instead of sound
           Product: Wine
           Version: 1.3.8
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msacm32
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: Nachanon_Vetjasit at hotmail.com
    Classification: Unclassified


I've been using Microsoft Sound Recorder to convert PCM (44100Hz 16-bit Stereo)
wave file to IMA ADPCM (44100Hz 4-bit Stereo), and saved to a wave file.

When I played the file in MPlayer, instead of the desired sound,
it played a loud static on the right channel, and a mashup of both
original channels on the left channel.

Mono encoding didn't affected though.

Other codecs are fine, except PCM (crashes; bug #26388), MS ADPCM
and MP3 (unavailable).


To reproduce:
- Start Microsoft Sound Recorder (use Windows XP version or below):
   $ wine sndrec32.exe
- Open some PCM wave file that is 44100Hz 16-bit Stereo.
- Go to File > Properties
- Click "Convert Now"
- Choose "IMA ADPCM" codec with 44100Hz 4-bit Stereo configuration.
- Click "OK"
- Save it to another wave file. (No matter play button is grayed out or not)
- Play that wave file with any player that supports IMA ADPCM.
  You'll hear a loud static on the right channel, and mashed-up sound
  on the left.

Another thing is after encoded, Sound Recorder saw a doubled length of audio,
MPlayer also saw so. When played, playhead moved twice the normal speed.
(Which is a strange behavior)

Note: I filed this as msacm32 since Sound Recorder is using it 
      directly for encoding.

Using WINE 1.3.8 (source) on Debian GNU/Linux 5.0 (i386: Intel Pentium 4
2.66GHz)
WINE Audio Driver: ALSA 44100Hz 16bit (Full Hardware Acceleration)
WINE installed without GStreamer support.
