NO SOUND ON MINT 12.

[silvialopez]

I'm a total newbie, so I ask for you to be patient,
Here's the thing: I already checked -through terminal- everything related to sound hardware and recognition of it. I checked the volume settings, the items on the device list, all of it.
When I set it on analog stereo and test the speakers, only the front left works.
When I try to listen to some music, it plays with "popping" sounds for like 5 minutes and then the sound dies but the Gnome media player interface is still there.

I guess the hardware is fine and I installed everything "by the book". So, if you have any solutions, please let me know.

My laptop is an ACER ASPIRE 5253 BZ851. AMD Radeon HD 6250. It runs MINT 12 32bit version.

Thanks a lot.
