mythmusic: 88.2KHz/24bit/6ch FLAC/WAV distorts

88.2KHz/24bit/6ch becomes distorted on playback when played in mythmusic. This occurs in both FLAC and WAV formats.
I've replicated this on two machines with very different hardware setups. One was an Audigy 2 ZS running through headphones over pulseaudio, the other was an onboard SP/DIF direct to an external amp (no pulse). Both played other formats fine, but heavily distorted when playing FLAC/WAV in this specific sample rate/bit depth/channel.
44.1KHz/16bit/Stereo plays fine. 48KHz/16bit/Stereo plays fine. 88.2KHz/24bit/Stereo plays fine. 88.2KHz/16bit/6ch plays fine. 96KHz/24bit/Stereo plays fine. 96KHz/24bit/6ch plays fine.
It's just 88.2KHz/24bit/6ch that distorts. If I re-encode the FLAC/WAV as 16bit, it plays back fine.
The FLAC/WAV also plays fine in other media players (including mythffplay) and passes a "flac -t" test.
mythffplay output: (a file that distorts) Audio: flac, 88200 Hz, 6 channels, s32
(a file that does not distort) Audio: pcm_s16le, 88200 Hz, 6 channels, s16
I suspect this may have something to do with changes introduced ticket #9930, but I can't be sure.
Both test machines are running v0.24.1-96-ge89d6a9 branch fixes/0.24
I've marked it as low/trivial as I suspect I'm the 0.0001% of the population that actually has media in this format.
