Hello,

I have installed Linux Mint 18.1 Serena on my MintBox2.

Everything works as expected except the audio output.

I followed all the instructions listed on the link :

$ pacmd

Everything looks fine, except that no sound comes out the speakers.

Please note that I plugged the speakers to the correct slot, according to the user guide : "Line-out S/PDIF out" (see page 4 of the user guide).

Any suggestion ?

Best regards,

Denis

Hello,

I was wondering : does the sound output behave like the video output, regarding the state of the connected device at boot time ?

If the video output is not connected, or if the connected display is not powered, at boot time, then the output is deactivated.

I'll try to boot the MintBox with the speakers powered and connected at boot time.

Best regards,

Denis

Hello,

I tried to boot while the speakers were connected and powered.

It does not change the fact that no sound comes out the speakers.

I can tell, however, that the audio electronic should be powered up.

Any idea ?

Thanks,

Denis

I finally found out what was wrong. The information that comes from the printed manual chipped with my MintBox2 is wrong. The audio input and the audio output are swapped.

I downloaded the user guide shipped with my MintBox.

And this the equivalent information from the Intense PC Wiki :

You can see that the information on the user guide is wrong.

Best regards,

Denis
