I forgot to mention, when I go into full screen it mutes all sounds not just the ones from dosbox. I was listening to slacker radio and on voice chat and as soon as I entered full screen I stopped hearing them. Sound was immediately restored after returning to windowed mode.

Interesting issue...

Instead of "going into" full-screen mode (I assume you use ALT+ENTER), change the config file so that it starts in full screen mode right away. You could also upload your config file onto here and have us take a look.

Are you using audio-over-HDMI? Did some googling and found this: http://forums.scummvm.org/viewtopic.php?t=115 … bebc8f2ff09caae

If all else fails, you can right-click the speaker icon in the system tray, then go to Playback Devices and right-click to disable any devices you don't want sound to come out of.

If that still doesn't help, right click the device you DO want sound to come from, then go to Properties->Advanced. Un-check "Allow applications to take exclusive control of this device" and hit OK.

Thanks I'll mess around with these things tonight. Yes I am using HDMI and yes it starts full screen by default. That forum talks about using an OpenGL option in scumm to allow higher resolution than 640x480, are you aware of a way to do that with dosbox?

Yeah...it has something to do with reading the manual and editing the .conf file.
Maybe those odd fullresolution and fullscreen options.

Dosbox settings...

Okay, so since it's an HDMI issue you can forget everything I said before. Instead, install the latest AMD Catalyst drivers and then poke around the Catalyst Control Center for HDMI- and/or HDCP-related options.

When I was running Windows on my nVidia-based HTPC, it had trouble with some full-screen stuff over HDMI due to HDCP until I tweaked some settings.

If you want to try OpenGL in DOSBox, set the following config options:
fullresolution=0x0 (or desktop or whatever resolution you want)
fulldouble=true (optional)
output=opengl (or output=openglnb if you don't want smoothing)
scaler=none (at least to start)
aspect=true (optional)

I solved my audio-over-HDMI problem using the guide at http://currysauce.org/2010/03/20/how-to-disab … graphics-cards/ . It involves altering the monitor definition so that the video card driver doesn't recognize it as being audio-capable, so it ought to work for ATI cards as well. (I think NVidia might have properly fixed the problem in the latest drivers.)

I would not have thought that problem would suddenly go away when running the game in windowed mode, though.

That link doesn't seem to work for me.

Forsooth, it seems to be down at the moment. Archive.org to the rescue.
