Help Sound only available on main speaker

[Wellan38]

Hi,

I have a Galaxy S I9000 running on Cyanogenmod 10.1.2.

Recently, I tried to change some settings in an audio configuration file (/etc/audio_policy.conf), because I read in a tutorial on the Internet that I could improve my bluetooth audio quality this way.

I didn't notice any change, until I rebooted my phone, and since then, I haven't been able to get sound other than from the main speaker (the jack connector, bluetooth, and "call speaker" (I don't know the name of this one) don't work anymore, which is pretty annoying).

I tried to put back the previous settings in the audio conf file, I also tried to wipe data in recovery mode, and it didn't change anything.

Do you have any idea how I could fix this?

Thanks
