Linux AudioEngine testers - Linux only
I'm checking the alsa driver log when playing HBR audio test file on ashecrow's machine.
And i suspect below channel mapping is wrong:
"[ 295.206626] hda-intel 0000:00:1b.0: azx_pcm_prepare: bufsize=0x10000, format=0x9817
[ 295.206701] HDMI: select CA 0x0 for 8-channel allocation: FL/FR LFE FC RL/RR

[ 295.207321] HDMI: ASP channel 15 => slot 4
[ 295.207363] HDMI: ASP channel 15 => slot 5
[ 295.207406] HDMI: ASP channel 15 => slot 6

[ 295.208150] hdmi_setup_stream: NID=0x6, new-pinctl=0x43
[ 295.208153] hda_codec_setup_stream: NID=0x3, stream=0x8, channel=0, format=0x9817
[ 301.750638] hda_codec_cleanup_stream: NID=0x3
[ 301.750724] hda_codec_cleanup_stream: NID=0x3
"

At first glance, channel 2~7 are emplty.

I donot have test environment so would any guy with HBR audio playing successfully provide some debug log?
Pleaes enable below two configs in your kernel .config:
3869 CONFIG_SND_DEBUG=y
3870 CONFIG_SND_DEBUG_VERBOSE=y

just capture the dmesg log when you're playing HBR audio, i need compare the ASP mapping part.

thanks
