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.

I've noticed in the past that one of the problems with ThinkPads is that they occasionally come with dodgy drivers. It's annoying – they are otherwise excellent machines, but it's a definite flaw. If you can figure out what your bluetooth chip actually is, the first thing I would do is go to the manufacturer's website, download the latest drivers for it, and install them. That might clear up your problem.

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.

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.

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