Only 2-channel devices are listed - no multichannel output in Win 7

[victorx]

I'm trying to use SC 3.6.2 with an external 7.1 sound card but the SC can use
only 2 channels.

When the server boots, it shows the list where the card appears with 2 out
channels - ignore the question marks that stand for Cyrillic characters:

Device options:
- MME : �������������� �������� ����. - Input (device #0 with 2 ins 0
outs)
- MME : �������� (Realtek High Definiti (device #1 with 2 ins 0 outs)
- MME : �������� (USB Multi-Channel Aud (device #2 with 2 ins 0 outs)
- MME : ���. ���� (USB Multi-Channel Au (device #3 with 2 ins 0 outs)
- MME : Stereo Mix (USB Multi-Channel A (device #4 with 2 ins 0 outs)
- MME : SPDIF In (USB Multi-Channel Aud (device #5 with 2 ins 0 outs)
- MME : ������ ������ (Realtek High Def (device #6 with 2 ins 0 outs)
- MME : �������������� �������� ����. - Output (device #7 with 0 ins 2
outs)
- MME : �������� *(USB Multi-Channel Aud* (device #8 with 0 ins* 2
outs*)
- MME : �������� (Realtek High Definiti (device #9 with 0 ins 2 outs)
- MME : �������� �����* (USB Multi-Chann * (device #10 with 0 ins *2
outs*)
- ASIO : ASIO4ALL v2 (device #11 with 2 ins 2 outs)
- ASIO : BEHRINGER USB AUDIO (device #12 with 2 ins 2 outs)

Audacity shows much longer list of devices. The desired entry is #19:
==============================
Device ID: 19
Device name: Динамики (USB Multi-Channel Audio Device)
Host name: MME
Input channels: 0
Output channels: *8*

What might restrict SC from getting complete list of devices?
Server.default.options.numOutputBusChannels is 8.
The card works in multichannel mode with native Windows applications.

I'm not sure (I'm no expert on the audio subsystem in Windows), but IIRC
scsynth uses PortAudio to hook up to a device, so there must be something
funny going on in there.

Hm, unless Audacity changed in recent versions, I thought it was also using
PortAudio. Maybe it initializes PortAudio with different parameters? I'm
guessing... this is way beyond me... just keeping the thread alive.

==============================
Device ID: 19
Device name: ДОМаЌОкО (USB Multi-Channel Audio Device)
Host name: MME

As you probably know, MME's latency is appalling for live use (over 230 ms,
last time I tried). I might try to configure ASIO4ALL to use the 8 channel
card and then tell scsynth to use ASIO.

To follow up on James suggestion of ASIO4ALL. On some windows machines it
is difficult to get ASIO4ALL to play nice with Supercollider, here is my
solution to it:

Thank you Jonathan and James - that solves the problem. ASIO4ALL provides
configuration options that I failed to find in SC.
