Hi Stefan,
I have got both devices. I could perform specific tests with them if you want and give me instructions. It can be a very slow process though because I have got almost no spare time, at least throughout January and February.
Thank you. Please confirm these items below with Clemens' jujuutils when you have a free time:
Thanks for these straightforward instructions. Here are the results.
1.They have both iPCR/oPCR. $ ./firewire-request /dev/fw1 read 0xfffff0000900 (oMPR) $ ./firewire-request /dev/fw1 read 0xfffff0000980 (iMPR) If they have, I can apply the same way to change sampling rate for all of models.
LaCie Speakers: --------------- $ firewire-request /dev/fw7 read 0xfffff0000900 result: 80ff0000 $ firewire-request /dev/fw7 read 0xfffff0000980 result: 80ff0001
Griffin FireWave: ----------------- $ firewire-request /dev/fw8 read 0xfffff0000900 result: 80ff0000 $ firewire-request /dev/fw8 read 0xfffff0000980 result: 80ff0001
2.They can respond to 'SINGLE' subfunction of 'AV/C Stream Format Information' command. $ ./firewire-request /dev/fw1 fcp 0x01ffbfc000000000ffffffff response: 000: 0c ff bf c0 00 00 00 00 ff 00 90 40 04 02 01 02 ...........@.... response: 010: 06 This is an example of Behringer F-Control A 202(OXFW970).

3.They can respond to 'LIST' subfunction of 'AV/C Stream Format Information' command. $ ./firewire-request /dev/fw1 fcp 0x01ffbfc100000000ffff01ff I have no devices which supports this command. I guess OXFW971 supports this.
