    Multiple Soundcards - Volume Control...

    I've just received my second souncard for the system, its a tiny little USB thing (only needed for headphones, so quality isnt a huge concern). I have tried setting RR to use soundcard 0, 1, 2, 3 and 4 but none of them will allow RR volume controls to adjust the USB soundcard's volume.

    The music and audio from videos is playing through the correct soundcard (because I adjusted winamp and mcplayer to use the USB soundcard) but just volume control isnt working.

    I am not able to change my systems default soundcard to the USB one because I am using the onboard sound for another RR instance.

    Running muliple instances of RR is working great, I can have one song playing through the car and another song through the headphones (from USB soundcard). So the only thing not working with sound is the volume control.

    just out of interest, are you running two screens? if so,. when running 2xroad runner, can you play two videos at the same time?

    I will soon be running two screens, just waiting to see if I can get it to work before I invest in a VGA roof-mount screen. I have a composite video roof mount screen, and the interface looks acceptable from the TV-out on my board, but I'd still rather go with a VGA roof mount or head rest screens.

    I havent been able to run two videos at the same time yet, but this is simply due to both RR instances trying to use the same video window. I will be testing with Zoom player on the second instance soon, let you know how I go.

    If the sound card setting is not working for you, it may just be because your USB card is placing the mixers together (speculation).. RR should try to list and enlist the cards as windows provides them.. I tested this with a Bluetooth Audio device and it worked.. never had a chance to try it with anything else..

    Check the debug log when you're trying to use the usb card (should be =1), and see what it says.

    I think my USB soundcard is #2 (I also have a Bluetooth device installed which shows as a soundcard output). Although I have tried with =0, =1, =2, =3, =4, =5, =6, and they all still control the onboard soundcard.

    Attached is my debug.txt file (which is identical no matter which soundcard setting is used - not sure if thats meant to be the case). I deleted a heap of lines which were just GPS data.

    On a side note, is there any way to use an external video player (not DVD player) so that I can use Zoom Player for playing videos? ZP can be setup to run multiple instances with different window names if that helps? Maybe RR can be coded to support the free ZP as a video player option for people who want to run multiple instances.

    EDIT: Also attached is my hw.txt file incase it helps. The USB device is the C-Media device near the bottom.

    Also, when running multiple instances of the video player, after hiding the controls (not moving the mouse) the controls are shown even if the mouse is moved on the second RR instance. Maybe the following line in frmMP.frm can be changed to only show the controls if the mouse moves over the current RR form position:
    Code:
    'If controls hidden, but moved cursor, show controls
    If Menus(IsLoaded("video_player.skin")).Visible = False And (SC = 0 Or SC = HideTime + 1) And lpos.x > 0 Then
    
    Maybe change to:
    
    'If controls hidden, but moved cursor, show controls
    If Menus(IsLoaded("video_player.skin")).Visible = False And (SC = 0 Or SC = HideTime + 1) And (lpos.x > Me.Left And lpos.x < Me.Left + Me.Width) Then
    There might be a few more code changes needed (such as the 'Count if Hasn't moved' code), but without being able to program with VB6 (coz I use VB.NET on my machine) I cant really test.

    Have you tried to map the master volume to an audio line ?

    All the audio lines are only lines of my onboard sound though. I tried "all lines" but that just controlled onboard sound. I also tried the "wave" line, but same thing.

    Which line should I try? Is the audio line list meant to update depending on which soundcard you have selected?
