Re: [sc-users] A(n old) PlayBuf problem

[Fredrik Olofsson <f@xxxxxxxxxxxxxxxxxxx>]

yes, indeed very strange.  (same problem in sc357 bytheway).

to temporarily solve it you can add a dummy DC.ar(1) and make it into a BinaryOpUGen.  then it seems to work...
sig = PlayBuf.ar(1, file, BufRateScale.kr(file), loop: 0)*DC.ar(1);	//ok
sig = PlayBuf.ar(1, file, BufRateScale.kr(file), loop: 0);			//bad
