Tried these cmds/routes to enable headphones (got from Raspberry PI wolfson card), but we got no output (except static noise and some "clicks") alsa_amixer -Dhw:0 cset name='HPOUT1 Digital Switch' on # Set path gain to -6dB for safety. ie mav 0.5Vrms output level. alsa_amixer -Dhw:0 cset name='HPOUT1 Digital Volume' 116 # do we want to clear the HPOUT mixers inputs? alsa_amixer -Dhw:0 cset name='HPOUT1L Input 1' None alsa_amixer -Dhw:0 cset name='HPOUT1R Input 1' None alsa_amixer -Dhw:0 cset name='HPOUT1L Input 2' None alsa_amixer -Dhw:0 cset name='HPOUT1R Input 2' None alsa_amixer -Dhw:0 cset name='HPOUT1L Input 1' AIF1RX1 alsa_amixer -Dhw:0 cset name='HPOUT1L Input 1 Volume' 32 alsa_amixer -Dhw:0 cset name='HPOUT1R Input 1' AIF1RX2 alsa_amixer -Dhw:0 cset name='HPOUT1R Input 1 Volume' 32 alsa_amixer -Dhw:0 cset name='Headset Mic Switch' on Tried also some other controls for speakers, but no audio output > > If you provide some kernel logs with the LOG_DEVICE in > drivers/base/regmap/regmap.c set to the CODEC spi device, I am > happy to sanity check what is going to the CODEC.

Thanks in advance Here's dmesg with LOG_DEVICE set (in this case to "spi-WM510204:00") [1] [1] - https://drive.google.com/file/d/0BxO6THtB865fS2NxUkdOa18zUlE/view?usp=sharing Regards Pstglia _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
