connected to a Viewsonic touchscreen ; USB (for the touch) and HDMI (for video/sound).
I have setup a trial of porteus on a mini pc, and while the touchscreen works perfectly, the sound is not working (I pointed to a simple HTML 5 webpage containing audio).
I don't know a lot about Linux but have been brought up on a diet of DOS 3.x-6.22, Windows and coding and I have managed to SSH to the device and done these steps:
First I needed a file to test the sound, so I did this:
Code: Select all
find / -name "*.wav"
Then I needed to list sound devices:
Code: Select all
aplay -l
Code: Select all

but when I try this
Code: Select all
aplay -D plughw:0,2 /usr/share/sounds/alert.wav
PS. I have also tried youtube but *wow* it plays videos without sound and at twice the normal speed!?
Can anyone help?
