Problem with CFStringCreateWithBytes on iOS5

Question

I have a strange problem with CFStringCreateWithBytes when migrating my app to iOS5.
When I build my application with iOS4.3, I can get the return string normally from this following code.
CFStringRef encodedData = CFStringCreateWithBytes(kCFAllocatorDefault, [response.data bytes], [response.data length], kCFStringEncodingMacThai, TRUE);
But if I build the same code with iOS5, the output from CFStringCreateWithBytes will become nil. I have already checked the response data that it is not nil.
Does anyone have this similar problem on iOS5?
BTW, the reason I have to use CFStringCreateWithBytes instead of just the NSString initWithData:encoding: is because my return data is encoded in TIS-620 which I don't think I can get the right result without kCFStringEncodingMacThai.

Answer 1

Yes.
I have the same issue on most sounds since the update to iOS5.
Most alerts, 'feedback' sounds like the keyboard click and the
lock/unlock are either far too loud (they are distracting and distort
because they are so loud) or inaudible. Occasionally they are 'normal'
but this doesn't last very long.
I can recover the sounds by making a volume adjustment, but after a
while things go screwy again.
