What do you mean by 4 streams? Is that the same as audio pins?
AFAIK this is the maximum amount of different streams played back at once. Before the patch I just attached, ALSA always used the "stream numbers" starting from the last one, which caused problems with assumed 8 streams because Christian's card only had 4 streams (his card had a single output only, though; alsa-info: http://sprunge.us/dbiB ).
So in addition to the patch I just attached I think we need to correct the stream count, _IF_ the 6/7-output cards only have 4 streams as well. But if those cards support 6/7 streams as well, all is OK.
Kaveri: 4 streams, 7 endpoints Kabini: 2 streams, 3 endpoints Bonaire/Hawaii: 6 streams, 7 endpoints Trinity/Richland: 4 streams, 6 endpoints Oland: 2 streams, 2 endpoints Tahiti/Pitcairn/Verde: 6 streams, 6 endpoints
Endpoints would be equivalent to pins as I understand it.
