I am getting either tinny or no audio on my Myth box with FC5 kernel 2.6.16-1.2080 and the 0.61 driver. Going in and out of Live TV a few times seems to make it come right but consistency of audio with recordings is not good. I'm not sure if this is the same problem as those  experiencing tinny audio with the 0.4x driver but the symptoms are similar. Output of ivtvctl --log-status below:

S-Video uses a different audio path. The microcontroller should be
turned off for S-Video and Composite. Check with --log-status that it
is not running. I also may have removed too much: there was a
soft-reset (reg 0x810) that I removed (since I now stop/start the
microcontroller), but I now realize that in the case of
S-Video/Composite that soft-reset might still be needed.
