# aptx and pulseaudio

Inspect BT packages:

* Install [bluez-utils-compat](https://aur.archlinux.org/packages/bluez-utils-compat/)
* Run `sudo hcidump avdt` and connect device
* See if `SBC` or `aptX` is used

See if there's a difference when installing the [pulseaudio-modules-bt-git](https://aur.archlinux.org/packages/pulseaudio-modules-bt-git/) package. After installing you need to restart _pulseaudio_ with e.g. `systemctl --user stop pulseaudio.service`.
