Many audience members were unable to hear the comedian's jokes during Saturday's gig at the Royal Concert Hall in Nottingham.
Richard Brown, 20, told the city's Evening Post: "A couple of hundred people walked out about halfway through. There were major problems with the sound from the start for people sitting along the sides."
He added: "The stalls and middle tiers were fine but lots of people were affected."
Refunds were offered to disgruntled fans and the problem was rectified in time for the second half.
