Mono sound output in windows 7

[LiamH]

Okay this is annoying me

Got a shiny new PC for my office at work, running windows 7 Ultimate just like my previous machine.

However I normally listen to music (via Spotify) through an in-ear headphone, I use just 1 ear-bud so I can still hear knocks at the door, phones ringing and my colleagues talking to me.

I can't for the life of me find an option to set the sound output to mono. Somehow it works on my old machine (still windows 7) but I'm not sure if that's due to the on-board sound being different and maybe not as up to date. A Google search seems to bring up a few responses from Microsoft that its no longer an option in win7.

Is this an overlook from Microsoft? it makes single earpiece devices unusable for programs with no inbuilt mono support, and people who are hard of hearing in 1 ear would only hear one channel of audio as-well.

Just posting this in the long shot hope someone has come up with a solution.

I know this is an old post but people may still be looking for an answer, and I have found it

About two or three months ago my left speaker in the laptop died. It did not bother me because most games and music seemed to sound just fine with one speaker. Movies and such usually get routed through the headphone jack to the surround sound system. But today I wanted to listen to a podcast and there was no sound. Windows volume meter showed there was infact something playing but it was not coming out the right speaker. I tried playing something else and it played fine. So I figured that the pod cast must be playing only out the left channel. So started my quest, to set windows 7 up to play sound in mono. Going to playback devices and configure for the speaker only had a stereo setting. I have a realtek driver loaded and nowhere could I find a mono setting. So I finally ended up at the realtek site and downloaded a generic vista/win7 driver.
It did not want to install because the driver was not signed. I uninstalled the old driver. I tried again to install the generic driver I had just downloaded without success. So finally I decided not to use the setup.exe and instead double clicked on alcupd.exe (the driver update program). Success. Only thing is that because I uninstalled the laptops sound driver, I no longer have any of the environment or equalizer settings. Not a big deal for me, If I need them I will just reinstall the laptop sound drivers. So I right click on the speaker icon in the taskbar and choose playback devices, then the properties for the headphone. I renamed headphone to Internal Speaker. Then under enhancements I chose Headphone virtualization. Success, now can hear both the left and right channels on the one good right speaker, with just slightly less volume.
I was able to hear my podcast just fine with the new settings.


So I guess "Headphone virtualization" equals Mono sound. Hey it works for me, maybe it will work for you.
