I got rocksmith 2014 remastared on steam and when i play i notice the volume of the game is very low like a whisper, i see game setting and check my laptop altavoz mixer and seems runing fine.

I write like a monkey in english 

Might have to do with the custom tones, when you add effects to the signal chain in RS the volume tends to drop. Since I play bass I tend to just swap to a clean tone any time that happens, if your playing guitar you may want to create a custom tone with only distortion. I haven't found the signal degrades too much with only 1 or 2 effects in the chain but any more than that and the volume degrades fast unless you use CFSM to boost the signal through the arrangements tab. You may also try to calibrate and only turn your instrument volume up around half way, that can help occasionally though not as much as creating a shorter signal chain (if your computer is running 100% volume on the RS cable more signal from your instrument will only cause compression not an increase in volume, almost like a tube amp.)
