hi
I have a portenta X8 and portenta max carrier , and I want to play some mp3 files via i2c and audio jack but there is no example on it
through portenta X8's tutorial , I'v connected portenta X8 via ssh and make and made some application about ethernet, but I have no Idea about play mp3 files,
I did a tutorial about audio test
"apk update && apk add alsa-utils alsa-utils-doc alsa-lib alsaconf alsa-ucm-conf && speaker-test -t sine -f 440 -c 2 -r 48000 -D hw:0,0"
and shell said,
speaker-test 1.2.5.1
Playback device is hw:0,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Sine wave rate is 440.0000Hz
ALSA lib confmisc.c:165:(snd_config_get_card) Cannot get card index for 0
Playback open error: -2,No such file or directory
I connected power jack so it suppose to activate the soundchip,
Is there sombody help me? (sorry for bad grammer, i'm bad at english)
