How can I couple my USB speaker through this menu? Tried putting device’s name in “Audio Device” (4936 is the device’s name), but nothing happens.
I there !
First of all : happy to arrive with you all on this forum !
Then, specifically to you, unlucky retroarch user who can’t use your bluetooth audio device : you should know that, until one hour ago, I was struggeling with the same issue (to tell you the truth, it’s been a 72h struggling…)
But the great news is just that we are too little-babies at knowing Linux, the solution is rather simple but I have to make a guess or two, before : you’re running Raspbian Buster on a PI4 ?
In this case, your problem is PulseAudio being used in place of blue-alsa, as Bluez doesn’t support alsa anymore… So you have to check that pulse-module-bluetooth is installed (it’s a Linux package, installable through Apt)…
when done, back to your terminal, just type
pacmd list-cards… Well, I must confess : I don’t remember the package name pacmd comes with…
But it should return something like :
1 card(s) available.
owner module: 30
device.description = “PSBTS31”
device.string = “94:23:6E:32:5D:2E”
device.api = “bluez”
device.class = “sound”
device.bus = “bluetooth”
device.form_factor = “headset”
bluez.path = “/org/bluez/hci0/dev_94_23_6E_32_5D_2E”
bluez.class = “0x260404”
bluez.alias = “PSBTS31”
device.icon_name = “audio-headset-bluetooth”
device.intended_roles = “phone”

Ok, you noticed that I’ve got one only card… It’s on purpose, but nothing changes the fact that this parameter is the critical one :
Now you have the crucial last element, you can get to the level-end-big-boss :
/home/pi/.config/retroarch/retroarch.cfg, the famous one and change two parameters :
audio_driver = "whatever, generally alsa"to
audio_driver = "pulse"
- audio_device = “whatever, generally nothing at all” to audio_device = “bluez_card.94_23_6E_32_5D_2E” (the parameter found with pacmd list-cards, minus it’s ‘brackets’) Have a test, drink a big glass of water and enjoy ! ^^ Oh ! By the way : I just discovered, writing this… Hum… tuto (not a real one, just a sketch)… that, after reboot (may it be a retroarch one or a Raspi one : I don’t have a clue), the ‘audio_device’ parameter may fall back to “”… Well don’t panic : After a test, I can tell that it’s no problem ! ^^
Hope it may help ! ^^
