alsa-info.txt from the alsa-info command

Wine programs play static instead of expected sounds, or sound is heavily
distorted, when ALSA plays back through pulseaudio.

Steps to Reproduce:
1. Start with empty wine prefix.
2. In the wine-git build directory, run: ./wine programs/winecfg/winecfg.exe.so
3. Click the Audio tab in winecfg.
4. Click the Test Sound button.

Expected Results:
A sound containing three tones is audible.

Actual Results:
Static is played.

Additional Information:
Using winecfg "Test Sound" gives white noise. When playing World of Warcraft or
other games, some sounds are almost recognizable through the static/distortion.
