I lost my sound the other day and I tried to delete pulseaudio then reinstall, then I tried to delete it and install alsa, It did not work and I had to reinstall everything; overall bad idea... now I can't have any sound.
Should I do a fresh install? I don't know how to boot an usb drive with GRUB...
Here's my sysinfo
