I boot Kali Live from a USB and everything seems to work except there is no sound. I find several "no sound" issues posted here several times here over the last few years. Resolution seems to be (generally) install/fix Pulsesound then reboot. However, I believe running Kali live shuts me out of a reboot style of fix. If so, then it sounds like I night need to turn on persistence so I could carry a fix across a reboot.

Key facts.
1. USB built from kali-linux-light-2019.3-amd64.iso, unmodified.
2. No persistence
3. USB boots fine and sound is the only basic function that seems not to work.
4. I cannot find any reference to sound in the boot log. (*** Although I will research this more.)

Is there a Kali Live user with any experience with this problem?
