Are these the errors referred to earlier as the "show stopper" for PulseAudio. Nope. Just an annoyance that can be fixed.<syntaxhighlight lang="text"> | Are these the errors referred to earlier as the "show stopper" for PulseAudio. Nope.

Result: It forking works now: pactl list short sinks | |||
There's a bunch of stuff about Cookies (one of PulseAudio's security methods), anonymous authentication, etc., but this is the simplest and works without changing PulseAudio's default configuration. | |||
=== Bluetooth (AKA Bluez) === | |||
==== Installation ==== | |||
opkg install bluez-daemon bluez-libs bluez-tools bluez-utils bluez-utils-btmon bluez-utils-extra kmod-input-uinput (other dependencies will install too) | |||
...and that's just the basic Bluetooth stuff. It doesn't include the firmware and driver for any specific hardware | |||
==== Hardware ==== | |||
Bluetooth hardware is fairly inexpensive these days. To 'future-proof' things as much as possible, order hardware with the latest and greatest version of Bluetooth. As of this writing, summer 2024, Bluetooth 5.3 is the contemporary version. | |||
A nice feature to have is a removable antenna. There are more compact devices that don't have removable antennas. And if you want super cheap device, step down to Bluetooth 4.x (still works great with speakers). | |||

Oh, one obnoxious note with Bluez and PulseAudio on OpenWRT is that as of this writing, even though Bluetooth 5.x supports two sets of speakers, just can't make a single controller connect to more than one speaker. Woof! | |||
Example of installing firmware and drivers for Bluetooth Hardware: opkg install <ins>rtl</ins>8761bu-firmware (bu is the version of the rtl8761 that was designed to work with USB 2.0, so if you're hooking up to a USB 3.0 port, this will work, but according to documentation, won't be optimized. PS: Bluetooth to Speaker will not exceed USB 2.0 speeds). | |||
