I dont think the gain is causing the distortion. It can be SSP settings DO you see distortion in one channel or both (try with headset) Also on Android, do you know kernel source for this, if vendor did release we cna check the settings there and configure the same here.

I have an Acer Aspire Switch 10 which seems to have the same audio chip like the Teclast and the other tablets mentioned in the bugzilla thread. I also had to change the interrupt index and tried the other driver with the fw_sst_0f28.bin-48kHz_i2s_master firmware, got overheating etc. etc. Finally following the advice in this thread I got to the same point, mfld driver with ssp0 firmware and applying the alsa settings as in http://mailman.alsa-project.org/pipermail/alsa-devel/2015-June/094080.html I get the distorted sound. I've been playing around with the mixer controls and wanted to report back my findings, maybe it can help. What I've found: 1) Sound seems only to be coming from the right speaker. If I turn off "Speaker R" there's no sound. Turning off "Speaker L" doesn't seem to do anything. If I turn off both playback stalls. Generally If I turn off any of the setting suggested in your mail playback stalls (mplayer). 2) By turning on "HPO MIX DAC1" "HPO MIX DAC2" "HP L" and "HP R" I get sound from the headset. Here also the sound is distorted and is only coming from the right channel. 3) Volume controls "Headphone" "Speaker" have no effect (I can't turn off the volume). My kernel is: 4.1.0 Modules: $ lsmod | grep snd snd_soc_sst_bytcr_rt5640 16384 0 snd_soc_rt5640 86016 1 snd_soc_rl6231 16384 1 snd_soc_rt5640 regmap_i2c 16384 1 snd_soc_rt5640 snd_intel_sst_acpi 16384 1 snd_intel_sst_core 69632 1 snd_intel_sst_acpi snd_soc_sst_mfld_platform 69632 3 snd_intel_sst_core snd_soc_core 155648 4 snd_soc_rt5640,snd_soc_sst_mfld_platform,snd_soc_sst_bytcr_rt5640 snd_compress 20480 1 snd_soc_core snd_pcm 106496 4 snd_soc_rt5640,snd_soc_core,snd_soc_sst_mfld_platform,snd_soc_sst_bytcr_rt5640 snd_timer 28672 1 snd_pcm snd 69632 7 snd_soc_core,snd_timer,snd_pcm,snd_soc_sst_mfld_platform,snd_compress soundcore 16384 1 snd alsa.state is "baytrailcraudio" with the setting suggested in your mail.

Yes, with ssp0 firmware, my board sound work too, but the mic don't work, when using arecord -f dat -t wav -d 5 foobar.wav, the record data is 0. hexdump foobar.wav 0000000 4952 4646 a624 000e 4157 4556 6d66 2074 0000010 0010 0000 0001 0002 bb80 0000 ee00 0002 0000020 0004 0010 6164 6174 a600 000e 0000 0000 0000030 0000 0000 0000 0000 0000 0000 0000 0000 * 00ea62c my analog microphone is connected to the IN2+ and MIC_BIAS1 codec pins I set alsa as : Stereo ADC MIXL ADC1 on Stereo ADC1 Mux ==> ADCL RECMIXL INL on RECMIXL BST2 on pcm1_out mix 0 codec_in1 on
