I tried, but to be honest, since I'm using linux, (about 6 years ago) I have noticed my lack of understanding in 2 things under this OS... One is the networking and dhcp stuff, and the other is the sound ^^ So I tried to do what you asked as precisely as I could be maybe I do something wrong :'( so went to alsamixer and tried to put everything at its maximum and unmuted everything. I even did this with thing unrelated to be sure! and I did this under pulsemixer too, but still nothing! I tried to look a bit on the net to see if something was missing. but I don't really know what to look for in the mean time! I saw a lot of peole asking to output command like `aplay -L` and `amixer`, so here I give them to you if you can notice somethign (I put them on paste.rs because I think it's way to messy for a mail but if you want me to paste them in mail next time, there is no problem ^^) - aplay -L : https://paste.rs/MYb - amixer : https://paste.rs/PaY > There's a separate issue that might explain why some people > are using a different card: some boards require a command to > enable some pins (called GPIO).

This is really helpful, again Thank you very much for you help ! PS: this device is still in use by my dad from time to time which is under windows and it actually work really well under Windows (now that I think about it, I only tried it with MAGIX software) Anthony.
