[alsa-devel] Intel Cherry Trail platform sound issue

[涂治河]

Hi All,

 

I get cherry trail tablet, and install ubuntu14.04.3, Kernel verison is
3.19.  The table using rt5672 codec with no sound output in ubuntu, but it
works in win8.

 

I get intel sst firmware fw_sst_22a8.bin from
https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tre
e/intel

The driver load the firmware successfully and I change some alsa mixer
items:

amixer -c0 sset 'codec_out0 mix 0 pcm0_in' on

amixer -c0 sset 'media0_out mix 0 media1_in' on

amixer -c0 sset 'media1_in Gain 0' 80% 

amixer -c0 sset 'media1_in Gain 0 Ramp Delay' 50

amixer -c0 sset 'media1_in Gain 0' off

amixer -c0 sset 'pcm0_in Gain 0' 80% 

amixer -c0 sset 'pcm0_in Gain 0 Ramp Delay' 50

amixer -c0 sset 'pcm0_in Gain 0' off

amixer -c0 sset 'codec_out0 Gain 0' 80%

amixer -c0 sset 'codec_out0 Gain 0 Ramp Delay' 50

amixer -c0 sset 'codec_out0 Gain 0' off

 

But there are some errors with dmesg:

I have no idea with the next step, so can anyone give a look?
