Hi, After some problems with Parallels 4.0 running on iMac Snow Leo, I decided to upgrade to 6.0 Now, I have the problem that openSUSE 11.3 remains silent, althoguh speakers are active. Trying different combinations on my iMac, I ran into a 'confusion matrix': Prl 4.0 / openSUSE 10.3: sound ok Prl 4.0 / openSUSE 11.3: sound ok Prl 6.0 / openSUSE 10.3: sound ok Prl 6.0 / openSUSE 11.3: sound not ok I would appreciate to get any ideas how to solve the problem. Thanks in advance! regards, Bernie
