No audio in Safari after Yosemite upgrade

I had the same problem and fixed it by going to settings - audio - output and changing it to internal speakers. It was on Soundflower (2CH) whatever that is. Hope this helps

Same here, TSN radio player won't work in Yosemite Safari but works fine in Firefox. I've just about had it with Safari compatibility issues. In this case the a simple radio stream won't even work.

I had the exact same issue since updating to Yosemite but it affected not only audio in Safari but also iTunes music, Youtube, videos, etc. Seems that it was resetting to Soundflower 2Ch or 64ch (found under System Preferences/Sound) instead of internal speakers or Headset as case should be. I could change it back to Internal speakers but every time I restarted computer it would go back to Soundflower setting and I would loose audio again. Turns out SoundFlower was installed with program called Splashtop Streamer/Personal and is poorly designed as it tries to take over audio like that!

How to get rid of it:

On the Desktop navigate to Go to Folder under Go menu and type in /System/Library/Extensions

Delete the entry called Soundflower.kext and reboot the computer.

Check the System Preferences/Sound and it should be gone from your list.

Your audio should now be back to normal.

I'm having the same problem. No sound flower here either.

Adam,

I'm in the "no audio" situation as well. I have audio in iTunes but none in Youtube - and I used to have audio. The audio just stopped working yesterday. Interestingly enough, if I post a Youtube video to my Facebook page, the audio is fine. I think there is something in Youtube and Yosemite that isn't compatible.

I'm having the same issue. Surprised nobody has found a solution (Apple are you listening)?

When you have Audio Hijack Pro installed: you have the option to install some extra's - Instant On

I removed Instant On from: Macintosh HD ▸ Library ▸ Audio ▸ Plug-Ins ▸ HAL ▸ InstantOn.driver directory

Did a new Instant On install: solved --> sound = ok now

I only had the sound issue in Youtue video's via Safari

Youtube video's via Chrome had the sound level ok, strange enough

I was having the same issue and this is what worked for me.

1. In Safari, clear your history and website data,

2. Then go to System Preferences in the Apple Menu and choose Flash Player.

3. Choose Advanced.

4. Under Browsing Data and Settings - click on "Delete All"

5. Check Delete All Site Data and Settings and click Delete All

Did that and then opened up YouTube on Safari and was finally able to hear audio. Hopefully it works for you too.

Here's how I solved this problem:

Go to Applications, then utilities, then Audio Midi Setup. Look to see if the Mute boxes are checked for your desired output option. If so, uncheck them. Worked for me!

Change your browser.

Apple, get your act together!

I just had this issue today. Nearly brand new MBA, complete clean install.

I noticed a Safari update coupla days ago. Then, yesterday that there was a new Flash, so I updated that. This morning, no sound. Did what a lot of other did. No joy. Cause I had stuff to do, went to Chrome as default and then, some hours later, it stops playing YouTube sound as well, so i look again.

Thanks man, this did the trick. Total Flash issue.

This procedure worked for me!

Solved after resetting Flash using steps solution vstuart6.
