I guess you are right about the mismatch betweens your clip's sample rate and the minimum your TV supports. I also have trouble playing sounds which do not have at least the minimum sample rate of 44100 (even when using plughw).
On my system there are several 22050 Hz files in /usr/share/sounds/purple which won't produce sound from HDMI out. Only after upconversion to 44100 I get sound (tested with sndfile-resample).
