Re: [alsa-devel] Griffin FireWave stream format information

Stefan or Jay,
Could I request you to get outputs against command in this message with FireWave?
Jay already responded, but

Based on this guess and according to its manual, FireWave should have 7 entries: $ firewire-request /dev/fw8 fcp 0x01ffbfc100000000ffff01ff 0c ff bf c1 00 00 00 00 ff 00 01 90 40 02 02 01 06 06

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

OK. Now we get to know how to change modes from 5.1ch surround sound to 'Dolby Pro Logic II' mode.

Yes. I made mistakes again. (I'm ashamed...)
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
The last two bytes should be 0x0606.
Within this two bytes, the first byte means the number of data channels and the second byte means type of the data channel. So in FireWave, 6ch PCM data channel is expressed by 0x0606, 2ch IEC 60958-3 data channel is expressed by 0x0200.
I'm sorry to trouble you but I request you to try the sequence of commands with these fixes...
Thanks

Thanks. Now we get to know the way to recover from '2ch IEC 60958-3 data' mode to '6ch PCM data' mode.
I note that this 'SINGLE' sunfunction of 'AV/C Stream Format Information' command can also be used to switch sampling rate instead of 'AV/C PLUG SIGNAL FORMAT' command (i.e. 0x00ff18009002ffff).
