2chnlben,
It is possible that software on your PC source could reduce the sample rate even though the router is not an issue.
For example, I have read (unconfirmed) that some older (pre Vista) versions of Windows may reduce sample rates implicitly in some cases. I believe this is possible though I do not recall specifics.
To avoid these kinds of problems, stick with newer computer platforms that are well suited for multimedia type apps, like Windows Vista or newer similar server versions of the OS (yes Vista gets a bum rap in corporate corners but it is essential to problem free playback off of PCs, I believe) or Apple.
