[FFADO-user] Jack/FFADO high samplerates

[Rolf A. <rol...@we...>]

Hello all,

Life is still good on this setup:
 * Kernel: 2.6.35-28-generic
 * libraw1394 2.0.7
 * FFADO head (r1983)
 * Firewire LSI FW643E2 controller card
 * 2-channel out/in DICE based device

Hardly any problems on all rates up to 96kHz.
We're now trying to take it to the next level: running at rates up to 192kHz.
Unfortunately this does not work at all: when starting JACK with FFADO

 * log shows streams could not be aligned
 * audible "chirps" occur regularly (although nothing is yet playing)
 * after 4-5 seconds FFADO gives up

I have not yet scrutinized this and I could rebuild FFADO with DEBUG if
necessary to show you any relevant logs; but before I go on, I was just
wondering if anyone has ever managed to get FFADO running with a DICE (or any
other) device at high samplerates (176.4 kHz & 192 kHz) and if there? If yes,
any suggestions, do's/dont's? If no, who's the culprit and is there a
construction site planned for this issue?

Best regards,

Rolf
