Multiple Soundcards - Volume Control...

**guino** · 07-12-2006, 11:13 AM

Sorry, that's a limitation on RRConfig..

You should look at the audio lines at the debug file when choosing the soundcard number.. Then set it to the number of the audio line in order of appearance, you may also try a custom vol command with the audio line name "VOL+;WAVE" etc.. to see if it works on the second audio card -- but I imagined that controlling multiple cards was not going to be just that simple.

I am trying the same thing and found that this idea worked the best.
I believe I am using the same USB sound card. Transparent green plastic, size of a memmory stick off ebay for about $10.00. I use it for rear audio, basically dvd only. I am also using a Bluetooth headset for voice control.

Go to your sounds and audio window under control panel. Select which ever sound card you want to be your default sound card. I use the USB sound card as the default. Then open winamp, go to the preferences menu and select the output selection. There you should find your USB sound card listed as C-Media (or what ever your driver is called for your USB sound card), you will also see Nullsoft output, direct sound output (this is your onboard sound card or default sound card) and wave out ouput.
Select your on board sound card and this will map all audio from winamp to your onboard sound card.
If you want to use you blue tooth head set as your microphone go back to sounds and audio window under control panel, select the voice tab and then select your default voice recording device. If you have the Voice SDK installed which I assume you do, there will be a few more configurations to make but it is pretty easy to figure out.
PowerDVD also has a configuration to map the audio to a certain device.
And that is how you can get specific devices to play in specific parts or your car simultaneously.
GOOD LUCK WITH THIS, it should work.

I have gotten winamp and MPC to play through the second sound card, I just can't get roadrunner to control the volume level of the USB soundcard.

Mine is transparent blue plastic, but yes, same card

I have my onboard sound set as default (so that windows sounds go through my stereo speakers), but I have tried setting the USB soundcard to default and still have the same problems (only now I cant get roadrunner to control the onboard sound).

BTW, I use direct sound output plugin for winamp, not wave out. You can choose which card it outputs on, and you get the nice fade effects when play/pausing a song.

Jag: Are you able to control the volume levels of both sound cards through roadrunner? If so, what roadrunner settings are you using?

The RRConfig only allows you to map a line to the default windows soundcard. Is there any way to make it show all lines of all soundcards?

Also, I noticed that in modMixer.bas the OpenMixer function redefines the SoundCard variable and doesnt set itself to any value, wouldn't this overwrite the rr.ini value and always use the first soundcard, 0 (zero) ?

Code:

Public Function OpenMixer() As Boolean
    Dim SoundCard As Double
    'try to open the mixer
    'if it can be opened, then the global hMixer variable will be set to it's handle
    If mixerOpen(hMixer, SoundCard, 0, 0, 0) = 0 Then
        OpenMixer = True   'life is grand, the mixer opened
        ReDim MixerState(0)
    End If

    'Test VolTable
    'ReDim VolTable(1, 2)
    'VolTable(0, 0) = 6
    'VolTable(1, 0) = 0.1
    'VolTable(0, 1) = 11
    'VolTable(1, 1) = 1
    'VolTable(0, 2) = 100
    'VolTable(1, 2) = 5
    
End Function

Then again, I could be way off....just want to get this to work so badly!

To tell you the truth I havent even tried to control the volume. I basically "set and forget it".

**Jarrod** · 07-13-2006, 07:16 AM

How are you controlling volume? Using hardware rather than software?

That Dim was not supposed to be there, the SoundCard variable should only be defined in modRoadRunner.. if that's there, either me or you have the wrong sources (or both).

I run my stereo through my head unit, volume control on HU.
For rear audio, headphones with volume control.
Voila..

Guino: I definately have the latest source (the readme.txt and request.txt file in the source zip has all the latest additions/changes). Could this have made it into the binary and be causing me issues?

Jag: I don't have (or want) the luxury of a head unit, thats the easy way out

Maybe I'll just have to settle for using headphones with volume control for the rear and remove all volume control from my rear seat RR skin.
