--- Comment #4 from Pierre Ossman pierre-bugzilla@ossman.eu --- I'll try changing as soon as I can find some time to play around with things. Although my rough calculation indicates that 3 packets per line should suffice:
1 frame/packet * 3 packets/line * 1080 lines * 24 Hz = 77 kHz
And in stereo mode it could be squeezing in 4 frames per packet, giving even more headroom.
