[alsa-devel] [PATCH 06/13] speakers: Change the way to make PCM rules/constraints

Thank you. Please confirm these items below with Clemens' jujuutils when 
you have a free  time:

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.

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 
........... at ....
    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.

It's better to receive your results till the middle of February.

I have a plan to post all of my patches with many fixments in the end of 
January. This may be my last RFCs. Then I recall for testing to some 
mailing lists like LAD. If everything goes well, I hope to post 
merge-request in the end of February.


Thanks
