Help Intermittent loudspeaker failure

[RSX901]

Hi android fans. Had this great phone for about a month now. My first android. To get to the point, a problem I've been having recently (not exactly sure when it first happened) but I'll go to watch a video and instead of the sound coming out of the loudspeaker, it comes out of the handset/phone speaker (not sure what you call it, the one above the screen for putting your ear to). Needless to say it's way too quiet to hear anything properly. It's happened randomly now about 6 or 7 times. I've had to restart the phone every time to remedy the problem. It's getting kinda annoying.

Also I think my headphone volume may be playing up. Not sure if it's related, but there's been times where at full volume music has been pretty underwhelming (I know about the dreaded EU volume cap (which I hope to remedy with a forthcoming root once I've read more up on the subject), no - it seemed even quieter). I'm almost sure there's something wrong because all of a sudden earlier today while listening to some sounds the volume jumped up to what seemed more akin to a maximum volume.

Could these two problems be related? And if so could anyone suggest what I could do to sort this out? Perhaps a factory reset (which I understand I'll have to do if I want to root anyway)? I really don't want to have to send it off for repair. I dunno if I could part with my new favourite toy lol.

Thanks for reading.

Bump cos the thread I replied to after creating this one got 35 views in the time this one got 10. An interesting stat on just how many people click on the top thread and then probably leave. Although of course the subject might have some influence.

Anyway, can anyone help? Would be much appreciated. (Starting to think I should have splashed out and got the S2. That forum's buzzing haha). Guess this phone's not that popular worldwide. Seems to be doing pretty well as a midrange phone in the UK. But then the S2's available everywhere. Not sure the same can be said for the W.
