I seem to have a problem with the sound control panel on my iMac 233MHz when running Toast together with a ZipCD USB writer. Every time I use the burner I am unable to get any sound from my Mac, either from the control panel or the control strip module. My machine is running OS 9.0.4, Toast 4.1.2 and I have recently installed the latest Multimedia update from Apple (althought I was having these problems with the previous software). Can anybody help.
