Would a supernova produce an audible sound due to the gas cloud formed during the explosion?

any material that can form pressure waves can produce sound.  even in interstellar and intergalactic space where the gas density is extremely low you can have shockwaves.

in and around stars the space is filled with gas as a plasma, plasmas have tons of oscillation modes including pressure waves, so certainly a supernova will create a huge pressure wave.

but if you're asking if the human ear can hear such a sound is a different question.  considering you'll be instantly vaporized long before the pressure wave hits you.
