I have not heard of any instances of it affecting audio equipment.
Because the affected caps were high frequency low-ESR types designed for
switching power supplies, I'd expect audio not to be much affected.

FWIW 20+ years ago when I was in the biz we did once get a batch of faulty
PSU smoothing caps. These mostly worked OK, but some had significant
leakage resistances, so would soon overheat and fail. I caught this within
a few days, but some sets went out! Managed to get almost all back from the
dealers, but a few were sold and one caused a problem by exploding in use.
Made a mess of an 'antique table' which we then paid compensation for.

So there is always a risk of such problems. But if the supplier is a good
one, and you check what is made, the problems are quite rare. The reality
is that no mass-produced product can be made with absolutely zero chance of
occasional failures. Some components will seem fine on even extended tests,
but then fail prematurely. Some component makers may be careful, but still
slip up at times.

Slainte,
