Audio trough USB headset not working DCS

[winchesterdelta1]

Hello,

 

I got an issue with my DCS headset Audio. Since i changed USB ports because i had to connect my new racing wheel i lost all audio trough my headset. Even when i connect it to the original USB port.

When i unplug the headset the audio does come trough my regular speakers.

DCS can see all my audio devices perfectly.

 

Troubleshoot steps i done "Plantronics DA70 headset":

 

*Restart PC > No solution

*Change USB port. > No solution

*Update game > No solution

*Check Game audio config > On Defaulth

*Changed game audio config directly pointing at Plantronics DA70 from the drop down menu > No solution

*Plantronics as default device in windows > Check

*Test with other games > Works perfectly

*Run DCS repair > No solution

*Test with SRS > Works perfectly

*Disconnect racing wheel > No solution

*Re-installed headset drivers in device manager > No solution

*Copied and renamed Config folders in DCS root and DCS Saved games > No solution

*Cleared content FXO folder > No solution

*Cleared content MetaShaders 2 > No solution

 

Only major changes to the system where:

- Installed Racing wheel.

- Moved headset to another USB port.

- Updated DCS.

- Updated SRS.

Hmm, the driver reports it only supports 1 channel (0x04 = SPEAKER_FRONT_CENTER).

Current code assumes a buggy driver here and tries to force stereo config.

I guess the device is actually mono and thus the stereo attempt fails.

 

Let's check the following:

add the line to your Config/autoexec.cfg file (create an empty one if there's none):

sound.channel_mask = 4

 

This will force DCS to use mono output.

If this helps, I will adjust the code to accept mono devices.

Thank you c0ff. I will try it out after work.

[winchesterdelta1]

Okay that worked perfectly c0ff. Sound is all back.

That was some quick fixing there. Highly appreciated. Thx.

I'm using my work head set. Had no clue it was only Mono LoL.

Ok. Great! I will add support for mono devices to the code.

Thank you for the effort!
