Hi, I have solved the problem following this: 1)
sudo vi /etc/modprobe.d/alsa-base.conf add at end -> options snd-hda-intel model=auto sudo restart 2) nano /etc/modprobe.d/modprobe.conf and at end -> options snd-usb-audio nrpacks=1 3) nano /etc/pulse/system.pa and nano /etc/pulse/default.pa change --> load-module module-udev-detect --->by --> load-module module-udev-detect tsched=0 4) Follow this ---> http://iam.tj/prototype/enhancements/Windows-acpi_osi.html Extract: add --> acpi_osi=!
