So I still haven't been able to figure this out and found tons of other people with various combinations of wireless intel cards / OS having the same or similar issues with bluetooth.
- an intel nuc (newest bios # 35)
- an intel ac3160 wifi/bluetooth card
- ubuntu 14.04 (newest kernel 3.18)
- iwlwifi-3160-10.ucode firmware
Bluetooth seems to work, I can put it on, I can select a device (a bluetooth speaker in this case) but after a second or so the connection goes back to "off" automatically.... So pairing does work, but it can never be selected as sound output.
Why doesn't this work and can I get it to? Maybe I should just buy an external bluetooth usb drive but it just annoys me intel hasn't been able to address this.
In this particular case, you can find our recommended drivers in this link: http://www.intel.com/support/wireless/wlan/sb/CS-034398.htm Intel® Wi-Fi Products — Linux* Support for Intel® Wi-Fi Adapters
Development support is only available through thehttps://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi open source community mailing lists. Intel does not provide support for development drivers. Which includes Bluetooth profiles.
So, since intel does provide a linux-driver for this wireless/bluetooth card, does that mean connecting to aptx a2dp bluetooth speaker should work?
And what support can intel provide on the recommended linux driver?
Please, understand that any support for Linux* will be found only in this link: https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi Open Source Communityhttps://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi
Please check with the manufacturer of your speaker what are their recommendations.
