Skipping Bluetooth Audio
January 18, 2014 9:17 AM Subscribe
I just bought a Lenovo T440s laptop, and the audio is skipping when streaming it to my bluetooth speakers, no matter what distance I sit away. I had previously been using my iPhone 5s for this, and it was wonderful. Is this par for laptops, is it fixable, or am I doing something wrong?
The laptop has the "ThinkPad Wireless 2 x 2 BGN with Bluetooth" option, which I believe is manufactured by Realtek (more formally perhaps "2x2 11b/g/n Wireless LAN M2 Adaptor"). Other than disabling power save, I can't find any configuration options to fiddle with.
Is it possible to lower the bitrate broadcasted (skipping is unbearable, bitrate I can handle)? Are laptops typically capable of streaming audio out, or am I spoiled by my iPhone? Would I have gotten better performance with the Intel ("Single Band 7260BN" or "Dual Band 7260AC") wifi/BT upgrade option? If you know you have this card, it may be worth it to just open it up and replace the PCI-e card.

Response by poster: There were newer drivers that were kind of difficult to install, although now in Device Manager a "Realtek Bluetooth 4.0 + High Speed Chip" (with new drivers) shows up instead of the Windows generic device (with drivers from 2006) -- still no dice.
In the course of checking this out I learned about USB micro adapters. Maybe if I open up the case the antenna will be easy to fix, but I think I'll plan on just buying a $15 dongle that's just always taking up a port.

Best answer: Bunch of people having similar problems with the Yoga 13" here, with some links to more recent drivers that have solved the problem for some people. Worth a try?
My guess is that power management is putting the bluetooth chip to sleep when it shouldn't. Try installing the very latest drivers from wherever you can get them & then try turning off power management in the bluetooth driver settings and see if that helps.

Response by poster: Well, ok, maybe I needed to reboot a couple more times? As of driver 1.3.754.3, there have been vanishingly few skips.
