Adding audio implementation with BT mode

[BleamX]

Please... I don't know if it's even possible, your app is already incredible but I'd like to be ( and I'm not the only one by the way ) able to play with my controller far away of my computer, and listening to the game by the jack plug in the DS4... It could be awesome and I hope you could make some miracles ^^

PS : sorry if my English is not really good, I'm french

Sorry, friend. But I don't think BT Audio is getting supported. This has been an issue for several years and it mostly turns into people complaining instead of helping. There was some work done into trying to get it working, but several issues kept popping up, like bad quality, or Windows muting the audio. It's not worth the trouble making it work good, when there are better solutions already out there.

The best way to get audio on the controller, is to use USB. But if you're using BT, a cheap $5 set of BT Headphones works just as well.

Thanks for your answer, appreciate it, thanks a lot for this super project!
I'll try to get a BT headphones

Probably not ever going to happen. Gotten pretty close but never got to a usable implementation. At this point, the main holdback is a lack of a library to encode to SBC audio in real time. Example showing the old progress that was made.

The only supported way to get headphone audio when connected wirelessly is the old Sony Wireless Adapter. Those haven't been manufactured in years and they were pretty expensive last I looked. I have not used mine in probably 2 years as I don't use the DS4 headphone jack much anyway.

Although it is from a Linux machine, here is another example showing roughly the same procedure.

The Sony wireless adapter works with dualsense or just dualshock4?

[Yohoki]

There's not really anything DS4W can do to workaround the adapter. It's not really an issue with DS4W, but with the adapter. The controller just doesn't pair with the adapter at all. It's either a driver or firmware issue. Sony needs to update the drivers to support connecting to these controllers, or update the controllers to connect to them.

since bluetooth support is limited to no audio, no haptic, no adaptive triggers, using normal BT adapters

You are incorrect here. Adaptative triggers, haptic feedbacks can be used through any generic BT adapter when connected to the PC, the problem is that NO GAME supports them, they are made to support the controller only via cable.

Once the ViGEmBus' driver supports virtual DualSense controllers it will be possible to do Real BT DualSense to Virtual USB DualSense emulation and workaround this. This process is the same as what DS4Windows does with DS4 controllers.

Regarding BT audio, it is, again, the same as the DS4: possible, but complicated to implement. Too much work for little benefit, which is why no developer is working on this

But also we know they use too much BT bandwidth, so who knows if actual BT adapters could handle that

A real Playstation 5 just uses a decent quality BT adapter in a good position, there is nothing special about it.

Sure. Was talking about workarounds for the official adapter, not ds4w. Seems like a modded BT adapter after all.

About normal BT dongles, tried 3 or 4. Didn't have much luck having stable connection with more than 2 dualsense controllers. With dualshock 4 controllers I don't have that problem. So I guess they use more bw or something related to that. Seems there are adapters that can handle more than 2 without problems, but still didn't have that luck finding one.

And I noticed even the PS5 Bluetooth only support dualsense controllers for bw reasons. If you need to connect a bt headset, you need to use another dongle.

Will look forward for dualsense vigem bus emulation support. That seems like a nice improvement if it can be done.

That's just Sony not wanting to implement it. Even the ps4 doesn't support BT headphones. You need a special adapter even for Sony's own Playstation Gold/Platinum headsets. I suspect this is more of a security lockdown than anything else. If a single headset+controller wasted too much bandwidth, then we'd be seeing connection problems when trying to connect 4 controllers at once on the consoles, and I can say for certain that 4 controllers works just fine on ps4, and most likely on ps5 as well.

I found some time ago wireshark of dualsense BW

https://www.reddit.com/r/SonyHeadphones/comments/qf2h75/bluetooth_bandwidth_wh1000xm4_dualsense_controller/

I think BT 5.0 protocol could handle fine but not sure if all drivers are prepared for this. Since most devices uses less BW.

TLDR

DualShock4: 76kbps

DualSense: 147kbps

And sometimes reach around 230kbps
