I am running linaro (not android). Version details –
Linux linaro-developer 4.4.9-linaro-lt-qcom #1 SMP PREEMPT Thu Jun 30 21:34:48 UTC 2016 aarch64 GNU/Linux
I am trying to get I2S sound output on the PCM/I2S pins on the low speed expansion connector -
16 PCM_FS LS_EXP_MI2S_WS (APQ GPIO_110)
18 PCM_CLK LS_EXP_MI2S_SCK (APQ GPIO_113) (ALPS_INT)
20 PCM_DO LS_EXP_MI2S_DATA0 (APQ GPIO_114)
Any suggestions on what the aplay command should look like?
aplay -D hw:0,0 /usr/share/sounds/alsa/Front_Left.wav
and I got the following error -
aplay: set_params:1239: Channels count non available
I also tried a plain aplay without arguments -
There were no errors, but I could not see any activity on the PCM lines.
