Installed 5.1.2 over 5.0.26 on OSx 10.11.5 host and got the following error message:
"Some AC'97 audio streams (PCM Output) could not be opened. Guest applications generating audio output or depending on audio input may hang. Make sure your host audio device is working properly. Check the logfile for error messages of the audio subsystem. Error ID: HostAudioNotResponding Severity: Warning” 5.0.26 worked fine with no errors so what could be causing this to pop up now?
