System.Media.SoundPlayer only plays through one speaker

Question

I have a sound I am playing through System.Media.SoundPlayer in C#. When I play it within visual studio it plays fine through both speakers. However, when I play it using System.Media.SoundPlayer, it only plays through the left speaker. I am using the code:

System.Media.SoundPlayer snd = new System.Media.SoundPlayer(Resource1.Radio);
snd.PlayLooping();

Does anyone know how to fix this?

Answer 1

I had the same problem and could fix it this way:

• stop windows audio service (command line: net stop AudioSrv )
• delete this registry folder: HKLU\\Software\\Microsoft\\Internet Explorer\\LowRegistry\\Audio\\PolicyConfig\\PropertyStore
• start windows audio service (command line: net start AudioSrv )

This clears any stored process-specific channel-wise volume settings, that may have been modified before (in my case this had happened through calling the waveOutSetVolume() API function).
