In this particular case, you can find our recommended drivers in this link: Intel® Wi-Fi Products — Linux* Support for Intel® Wi-Fi Adapters
Development support is only available through the 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: Open Source Communityhttps://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi
Please check with the manufacturer of your speaker what are their recommendations.
