I found out, that this issue is probably related to all 24bit 6ch sound files, not only FLAC and WAV. I reproduced the problem only in Windows 7 64b, in XP everything seems to be ok. The problem is in output plugins - out_MMDS and out_wave, both give error "invalid parameter" when creating sound buffer (WaveOutOpen, CreateSoundBuffer), I have no idea why and why in XP not. Peke, could you do more research, please?
WASAPI output plugin plays these files correctly...

Maiko WASAPI plugin play only two chanels and report that ">2" error, but have found that old winamps out_ds plays them without problems (the one we used in MM).

I uploaded out_ds to ftp.

Peke, since Michal has a lot of other stuff to work on, please look into out_DS plug-in sources and try to find out, how to call the initialization so that it doesn't fail.

Note, that this issue will also be fixed by fixing 0006469, but it would be nice to have this one fixed anyway.

As talked over IM WAVE_FORMAT_PCM do not support Multi channel and out_MMDS needs to use IDirectSound8 instead of IDirectSound along with WAVE_FORMAT_EXTENSIBLE packed record to allocate buffers correctly.

Will see if there is way for easy fix.

Tested in Win XP and there is no problem playing 6 channel FLACs and WAVs by using out_MMDS.dll output plugin.

Out_wave verified 1322

have you received sources/changes for out_mmds?

peke: yes, I do. It does not play 6ch audio in Win7 and has buggy playback in XP. I have no time for debug now, other things have higher priority, will see later.

Certainly, for now out_wave works as it should, I know it is buggy but I was just starting to rewrite (See System Folder in sources).

I wonder if we should open new ticket due the fact that original bug issue is solved with out_wave?
