Dolby Audio keeps turning off randomly on Lenovo T560

[Boris1012]

Dolby Audio Driver on Lenovo T560 keeps turning off randomly for unknown reason (already diagnonised system, troubleshooted problem, etc.), had to manually turn it on everytime when it turns off, can be frustating especially when listening to music, using skype or watch videos on YouTube. The problem only started recently, not sure if it is something to do with Windows Updates that affected the driver. Please advice on how to fix the problem and if possible Lenovo please do address the bug, thank you!

Hi.

I have the exact same problem on my ThinkPad 13 (or S2 depending on where you live). Dolby Audio turns off randomly, but I've found that it turns off every time I change song in Spotify. It also happens randomly when Spotify is closed. It tends to happen less when I turn it back on using the Dolby Audio app instead of the Lenovo Settings app. This problem started happening around the same time you posted your post. (Ca. 20th Oct. - 1st Nov.)

This is extremely annoying, and I hope that Lenovo or Dolby releases a fix soon.

Hello, I'm facing the same problem on T440P. It has a Realtek HD Audio Driver 6.0.1.7746.

I cheated by using drivers for other machines (T460) including Realtek Driver versions 6.0.1.7855 and 6.0.1.7898 but the problem persisted.

Dolby Digital Plus would randomly switch off, sometimes even right after boot up and no applications is running.

Please help.

Don't know why but for some unknown reason Dolby Audio Driver now seems to work properly, maybe with latest software update that fixed the bug
