Can anyone help me determine whether my TF201 has a problem with the sound? I suspect that one of the sound channels may not be wired up to the internal speaker, although both channels sound fine on headphones. When I listen to the built-in alarm sound "Cesium" through the headphones, it goes "bing bong bing", where the "bing" is in the left ear and the "bong" in the right. But through the internal speaker this sound just goes "... bong ..." - the "bing"s are missing. What do other people with this tablet hear when playing the Cesium sound through the speaker? I'm running Android 4.0.3. I also notice that the sound on Skype and on many YouTube videos is too quiet through the internal speaker. I wonder whether I'm only getting one of the channels. Can anyone think of other ways that I can test whether the internal speaker has a problem with the left audio channel? How could I determine whether it's a hardware or a software problem? Are there any apps that would help me test? Thank you!
