Oh, I made a mistake again...
The subfunction should be 0xc0 (Single) instead of 0xc1 (List). 'Extend Stream Format Information' command don't allow ctype=control for List subfunction.
These are correct commands: (for 32.0kHz) $ firewire-request /dev/fw8 fcp 0x00ffbfc000000000ff0090400202010200 (for 44.1kHz) $ firewire-request /dev/fw8 fcp 0x00ffbfc000000000ff0090400302010200 (for 48.0kHz) $ firewire-request /dev/fw8 fcp 0x00ffbfc000000000ff0090400402010200
If one of them are accepted, the stream format is changed for 2ch IEC 60958-3 at indicated rate. To confirm it, please execute this command again: $ firewire-request /dev/fw8 fcp 0x01ffbfc000000000ffffffff Response should be: 0c ff bf c0 00 00 00 00 ff 00 90 40 0[234] 02 01 02 00
To recover to 5.1ch surround, please execute this command: (for 32.0kHz) $ firewire-request /dev/fw8 fcp 0x00ffbfc000000000ff0090400202010200 (for 44.1kHz) $ firewire-request /dev/fw8 fcp 0x00ffbfc000000000ff0090400302010200 (for 48.0kHz) $ firewire-request /dev/fw8 fcp 0x00ffbfc000000000ff0090400402010200 (for 96.0kHz) $ firewire-request /dev/fw8 fcp 0x00ffbfc000000000ff0090400502010200
To confirm it, please execute this command again: $ firewire-request /dev/fw8 fcp 0x01ffbfc000000000ffffffff
Response should be: 0c ff bf c0 00 00 00 00 ff 00 90 40 0[2345] 02 01 06 06
