Overall, it works nicely for the first few minutes, then the audio begins to skip. This happens regardless of the audio client employed (mplayer, vlc/cvlc, radiotray, etc.). Based on mplayer's errors, it appears to be a caching issue:
A: 16.2 (16.1) of -0.0 (unknown) 0.1% 0% Cache empty, consider increasing -cache and/or -cache-min. [performance issue]Since the issue appears to be independent of the client, I'm making the assumption is on the RPi end. I'm hoping that this can be fixed. More research in my future, I guess.
