Appears to work with this too (stereo and 4-channel modes) but the point was to test with creative's drivers that usually always have some issues

Technical explanation (if anyone is interested..)

There are WAVEFORMATEX and WAVEFORMATEXTENSIBLE (extension of WAVEFORMATEX) structures that describe the sample format.

"Original way": set format type = WAVE_FORMAT_PCM and channels = 1 or 2 (+frequency and other misc data but they aren't important here) 3 or more channels are not allowed in theory (says the spec..) but it does work with some drivers. (NForce2 and KX appears to work) WinUAE 1.3.3 and older used this.

"New way": 1 or 2 channels = use old system. 4 channels: use WAVE_FORMAT_EXTENSIBLE which requires speaker position information. Unfortunately there are still some problems.. Many sound drivers don't support plain 4 channel audio (2, 5.1 or 7.1 are the most common "always" supported channel combinations) There is also "ALL" speakers parameter but again not all sound drivers support it either.. (ALL seems to really mean "driver can guess the speaker positions")

Currently WinUAE initializes sound in max 3 passes (if 4 channel mode enabled)

1: use WAVE_FORMAT_PCM and 4 channels. Failed? go to pass 2.
2: use WAVE_FORMAT_EXTENSIBLE with "ALL" speaker configuration. Failed? go to pass 3.
3: use WAVE_FORMAT_EXTENSIBLE with "QUAD" (front left, front right, rear left and rear right) speaker configuration.

(Only pass 3 works on my PC)

I guess there will be pass 4 in future version that creates 5.1 stream with 2 "extra" channels zeroed for best compatibility.

I really like it when every driver does things slightly differently..

Played a bit with beta #9:

4 Channel surround doesn't seem to work, I only get sound on the front channels (Creative Audigy 2 ZS with Creative drivers).

Changing from 4 Channel to Stereo or back mutes all audio, but can be restarted if the game that is running also restarts audio (tried with Turrican II sound menu, just select the same track again).

Do you need any logs?

EDIT: Switching between interpolation modes also mutes audio.

NForce2 MB 4-channel sound works now (tried with old Audigy 1 but didn't find my original driver CD and Creative's driver updates need original driver installed, really great customer support..)

4-channel sound works now on my Audigy 4 with the newer 30.12.2006 beta 9 build

I can't duplicate any of these problems.. "SOUND:xxx" parts from logs perhaps helps..

Anyway, I will release 1.3.4 officially later today if this is the only problem left

It is done, thanks for testing and comments.
