Sound on Linux
HDMI audio/ AV out audio
To test audio on Radxa Rock, you can run the following command:
root@radxa:~# speaker-test -t wav -c 2
the output is
speaker-test 1.0.25 Playback device is default Stream parameters are 48000Hz, S16_LE, 2 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 48 to 32768 Period size range from 16 to 3072 Using max buffer size 32768 Periods = 4 was set period_size = 2979 was set buffer_size = 32768 0 - Front Left 1 - Front Right Time per period = 2.061311
And you can hear the audio from HDMI.
Squeezelite on rock with USB DAC
Working on getting squeezelite working with a USB DAC to play with Logitech Media Server. You need Logitech Media Server otherwise squeezelite is worthless without it. I have several instances of LMS around my house
Download Squeezelite AMRV6hf from here
https://code.google.com/p/squeezelite/downloads/detail?name=squeezelite-armv6hf&can=2&q=
sudo mv ./squeezelite-armv6hf /usr/bin/squeezelite
sudo chmod ug+x /usr/bin/squeezelite
Plug Dac into USB and type
squeezelite -l
It lists all sound devices. I typically use the "front" device. Then type.
squeezelite -o front:CARD=DAC,DEV=0 -n ANYNAMEYOUWANT -s YOUR . SERVER . ADDRESS -a ::16:
i.e.
squeezelite -o front:CARD=DAC,DEV=0 -n RadxaRock -s 10.0.1.99 -a ::16:
Unfortunately I can't get it working in 24 bit so far. I'm close with a few pops and clicks and hopefully can get it. And anybody that has any ideas I'm all ears.
