Because My A/V receiver is not handy, so i call for some volunteers to help test the HDMI HBR patchset before it could been accept by Takashi.
The patchset is already sent to alsa-devel maillist in RFC version:
You can also download the *Three* patches from Here:
(please download patch1/2/3)
Please apply these patches to Takashi's latest sound tree:
Besides the normal test about HBR stream playback, also make sure it works well during below two tests:
1) Play HBR stream. (8 channels)
2) in command line, use "speaker-test" and specify 8 channels, i.e.
speakert-test -t wav -c 8 (your-hdmi-card)
There's one bug in alsa-driver that the new channel mapping does not update, this patchset intended to fix that.
You need also change the HDA-Intel.conf at comment #446:
please let me know if there's any pending risk of this patch before it's upstream, thanks in advance!

I'll test it myself, but could you please also make a kernel compile with the patches and test them. Note that there are 3 patches there.
These tests are needed so that the patch could go into kernel mainline.
Thanks, cheers, Attila
