Shane: the first two patches should address the two bugs you reported, i.e.
- multi-channel HDMI audio playback problem
- first half-second audio samples missing
These two bugs was reproduced and fixed in the combination of G35 SDVO HDMI + Yamaha RX-V1800 AV receiver. The first problem cannot be verified in G45 system because we still cannot make G45 work with Yamaha. The second problem is interesting in that it can be fixed by the second patch in G35, but still remains in G45.
Hi,
Ok mixed results here. I'm using this for my test signal: http://www.csy.ca/~shane/51test.wav
when using: aplay -D hw:0,3 51test.wav
Front and rear left and right are correct but centre is missing. The order in the wav is: front left centre front right rear left rear right sub buz
The order assumed here doesn't match with ALSA mapping. In ALSA, front left front right rear left rear right center LFE
Better to test with speaker-test program whether the mapping is correct.
