More details required.

In what way is it not working? How are you trying to listen to it? Through the 3.5mm socket? Through your TV speakers?

So you are using a USB Sound Device ?

No way to sort it out. I will contact the factory because i guess it could be a failed piece...is could not be so "unfriendly use"

Which OS are you running on your Pi? What commands did you use to update it?

If you're running Raspbian, open a terminal and type...

Code: Select all

sudo raspi-config
Go to Advanced Options and there's an option called Audio. This allows you to control where the audio is sent. Try setting it to Force 3.5mm and plug your headphones into the headphone jack socket. Do you get sound now?

Thanks now is working, despite watching video on internet (and internet in general) is extremely slow and not synchronized with the audio.
I got 2pi some weeks ago, followed all the instructions as per infos on the web site, therefore I do have a raspbian OS.

It can be very slow if you run high quality videos, because some web browsers do not take full advantage of all of the cores. 320x240 videos should run fine. Anything video quality above that, may need to be downloaded, and run through dedicated playback software (omxplayer is a popular choice).

This is not correct. Browsers based on webkitgtk3 (epiphany, kweb3) use hardware (GPU) accelerated video playback inside the browser. It works quite well, if the video area is not too large.

Older versions of Iceweasel only utilised one core. Playing any video above 320x240 was next to impossible. These days, you can watch videos on YouTube at reasonable resolutions after a bit of a stuttering start. Without knowing the setup the OP is using, or what the quality of videos they are playing is, it's hard to say what's happening. USB audio has never been an issue for me though (except when trying to run things in real time through a USB hub (guitarix)).
