N900 sound issue and another issue
 

Hello.I have my Nokia from 5 days.
I have some crackling issues. The issue is presented in follow 3 cases:
1.Right before the ring sound, I very ofren have crackling
2.Sometimes during the conversations I have crackling
3 When I switch between sounds or movies in the player
For my surprase when I play someting - movie or mp3 - the sound is clear.
I need advice, what to do?

And another issue.It is not big deal and I guess it has somoting to do with options. When I plug my N900 into USB and select "Mass storage" from my computer, under Windows Explorer I can see only 4 GB microSD. Yes I have this microSD in my N900, but How can I access N900 32 gb storage?

Thank you
