I wonder if Apple has too many ex-Microsoft people doing systems work.Audio generated by MuseScore should be sent to whatever audio output device is selected in the Sound output preferences dialog.Īudio generated by MuseScore appears to very strongly prefer to be sent to the MacBook laptop speakers, regardless of which output device is chosen in the sound output preferences. Rebooted into 10.8.5 and everything works fine so far. Rebooted into 10.6.8 and everything works fine. Tried some of the suggestions - zap pram, permissions, audio midi, etc. speakers plugged in, played through internal speakers - with no speakers, no sound. Sound control panel showed it constantly switching back and forth from internal to headphone with the sound actually reversed - i.e. Was using 10.8 and all of a sudden sound went flaky. With 2 small Sony SRS-88 powered speakers I also use Audio Hijack Pro for general sound enhancement and SRS iWow in iTunes I only went to 10.8 because Apple won't accept iPhoto orders from older versions anymore. I have both 10.8.5 and 10.6.8 external boot drives. Have already been through dead internal drive, new power supply, top half of screen is dimming.
Sound output issue could be 10.8 NOT hardware I have used Disk Utility to "VerifyRepair Permissions" (which was needed) and also checked "Verify Disk" (which didn't find anything wrong).ĭoes anyone have any suggestions on what to try next? I have reset PRAM and SMC Power Management 4-5 times with no success.
Without that option, I can't "choose" the Internal Speakers to turn them "on". There were NO OTHER options available so, Built-in Speakers was no longer an option. The Mute Box is unchecked and the Volume Curser is grayed out. Remembering I had to change back the audio settings, I opened Preferences/Audio/Output and the ONLY selection listed under Name/Type was Digital Out/Optical digital-out port. When I disconnected the external speakers, and restarted my MacBookPro, I heard the Startup Chime (so I knew the speakers work) but, when I tried to listen to ANY audio through the Built-in speakers (from iTunes, video, clips from the internet, etc.) no audio was heard. Since I could hear the audio through the external speakers, I forgot to reset any settings in the Preference/Audio window. The Rosetta software gave instructions to Open Preferences/Audio and choose the USB mic/headset as the input/output device (this muted the built-in speakers on my MacBookPro.Īfter completing the lesson, I unplugged the USB mic/headset and plugged in my external speakers into the Audio OUT port. I was using Rosetta Stone software and it required plugging in (and using) the included USB mic/headset. My Built-in Speakers worked perfectly until. I have a 17 inch i7 Intel Chip 2010 MacBookPro running OS 10.8.5 that works correctly in all respects except that my Built-in Speakers stopped working.
