Detailed context

I tried to run alsamixer while on the ergocub-head, but it produced the following output:

cannot open mixer: No such file or directory

I also launched lspci -v, getting the following output, but no sign of audio cars:

Hi! me and @Gandoo connected the speaker to the Xavier (ergocub-head) and tested, It seems working properly:

Give us a feedback about the functioning of the speaker!
