HLE Audio: Increase frame position by input buffer sample rate (#5049) 

* HLE Audio: Increase frame position by input buffer sample rate

Currently the frame position moves ahead by the number of samples
output, but thats a fixed number based on the 3ds native sample rate.
Instead, based on a homebrew by cyuubi and looking at the lle audio,
this sample position should be moved forward by the number of samples
from the input buffer that was read, based on the buffer's sample rate.
