Hi, These patches make some changes to mixer on Audigy 1 and Audigy 2.
Changes:
- new FX bus allocated for Wave Stereo playback ("Wave Playback
Volume")
- new "Master Playback Volume" control - controls output volume for
all channels (implemented using DSP code)
- new controls "PCM Front Playback Volume", "PCM Surround Playback
Volume", "PCM Center Playback Volume", "PCM LFE Playback Volume" for
multi-channel (5.1) playback
- new controls "Front Playback Volume", "Surround Playback
Volume", "Center Playback Volume", "LFE Playback Volume" - there are
just before master volume - controls mix from PCM (5.1) and Stereo
Mix (Stereo Wave, AC97, ...)
- new controls "Stereo Mix Front Playback Volume", "Stereo Mix
Surround Playback Volume", "Stereo Mix Center Playback
Volume", "Stereo Mix LFE Playback Volume" - used do control volume of
mix from stereo sources (make mirroring to 5.1 for stereo)
Audigy 1:
- removed AC97 control "Master Volume Playback", "Master Mono Volume
Playback", "PCM Volume Playback", "PCM Out Path & Mute" - there are
unused
- uses Philips 6 channel DAC for all channels, WARNING: all analog
sources are routed throught DSP (if you want listen line in you must
set "AC97 Playback Volume" and "(" set capture on "(" "Line in"
and "Capture" ")" or "(" capture on "Mix" and volume for "Line in" ")"
using Philis DAC has some advantage - Same volume levels for all
channels, I think better signal, ..)
- analog signals can by routed to all channles
disadvantage - all analog signals must be routed throught DSP -
(confusing selecting analog inputs and volumes for analogs inputs)
I tested 5.1 playback, wave stereo playback midi playback and analog
playback.
I hope I don't break something (OSS mixer, AC3 playback, optical
input, output, coaxial input, output) - not tested.
Names are not very well choosen (some needs rename).
Maybe I can remove "Front Playback Volume", "Surround Playback
Volume", "Center Playback Volume", "LFE Playback Volume" and use only
controls for "PCM" and "Stereo Mix"
devices:
front - routed throught front channels of 5.1 PCM ("PCM Front"
controls volume)
rear - routed throught rear channels of 5.1 PCM ("PCM Surround"
controls volume)
center_lfe - routed throught center, lfe channels of 5.1 PCM ("PCM
Center" and "PCM LFE" controls volume)
default (stereo) - routed to stereo mix ("Wave" controls volume)
Any suggestions, bugs, ...
