WAV file is default sounds I got from Windows Media directory so it must be standard.
I made reset and reboot and send commands but nothing no happened after
Please avoid # before the commands. I put this to reflect shell terminal should not be included while executing the commands
one issue with your command again, include double quotes to mixer name like below.
amixer -c “tegrasndt210ref” cget name=“I2S4 Mux”
Did you dumped this info after reboot as suggested and without executing any commands. Reason is seeing ADMAIF5 is connected to I2S4 Mux which should not be the case
numid=549,iface=MIXER,name=‘I2S4 Mux’
; type=ENUMERATED,access=rw------,values=1,items=53
; Item #0 ‘None’
…
: values=5
Just for debug purpose, perform below command and try on userspace sound playback.
amixer -c “tegrasndt210ref” cset name=“I2S4 Mux” “ADMAIF1”
Tried it and test is not make sound but userspace sound playback is WORK !!
Ok, this confirms Userspace audio is working. After boot with below command should show mixer value=1 (i.e ADMAIF1). Make sure I2S4 Mux is not set manually after boot and if ALSA conf set properly during boot, it should straightaway work on userspace.
amixer -c “tegrasndt210ref” cget name=“I2S4 Mux”
I made restart ( reboot) and sound is work without additional commands.
Thanks !
You are a very good specialist and I need help in other things.
I created my own board with use of UARTs and GPIOs . I need help to open all this ports in Nano SOM :
and also work with LIRC
Can you provide solutions ?
Hi chaplin,
Am audio expert but just to understand and guide you to right forum. Are you looking to configure these pins as GPIOS OUT or IN?. If so PINMUX configuration should help here.
If above is not the one looking for, then you can raise a separate Jetson forum query to get help on this.
it’s a pity , because question about LIRC was asked in 2014 and still nobody answer…
Ok, Please raise a separate forum query specific to this for tracking.
