The following link takes you to a support page on Cakewalk's site where you will find a hotfix to address a single issue: http://www.cakewalk.com/support/kb/kb20080207.asp This hotfix has made all the difference for a customer who has a TC audio interface. Perhaps this hotfix can make life easier for some of you too. But as the quote from the page below says, if you have not experienced the situation described, there is no need and no benefit to downloading this hotfix. If you have any questions about it, please address them to the support people at Cakewalk: support@xxxxxxxxxxxx or 1-888-CAKEWALK. *** This hotfix addresses a single issue that was reported by a few customers while running SONAR 7.0.2 only with certain ASIO drivers. While stopping and restarting playback, or if another application accessed the audio device while SONAR was in use, occasionally you could get the following error message: "Unable to open audio playback device. Device may not support the current project's audio format or may be in use". If you have encountered this problem in SONAR 7.0.2 please download the appropriate hotfix for your version of SONAR and copy the file to your SONAR program folder. If you do not have this problem there is no need to get this update since it addresses exactly this one problem. *** Regards, Bill Bill McCann Founder and President of Dancing Dots since 1992 www.DancingDots.com Tel: [001] 610-783-6692 PLEASE READ THIS FOOTER AT LEAST ONCE!
