How to fix this warning "trying to set for simultaneous audio play" but i am not able to get that option. Assist me to get that option (or) any alternative solution to get dual Bluetooth play on two paired headset.

what OS do you use? maybe you can refer to this

"https://github.com/microsoft/vcpkg/issues/9936"

[MJD]

The OS on my target machine is a custom Linux distribution based on the Yocto Project. The specific configuration used is 'imx-image-full,' which includes a full set of software packages and libraries tailored for the i.MX8M Plus EVK board.

[joanxie]

you can refer to the link I sent to you before, for pules audio usage on this bsp, you can refer to the chapter 7.4 PulseAudio input/output settings of enclosed file

but still not able to play on two Bluetooth paired devices.

Does this IMX8m Plus Evk broad  with Azure Wave BT/Wifi supports for dual audio play on two paired Bluetooth devices?

[joanxie]

what do you mean dual audio play? do you need playback audio on two Bluetooth devices in the same time?

[MJD]

Yes! I need playback audio on two Bluetooth devices in the same time.

[joanxie]

I confirmed this doesn't support, only A2DP of aw690（auto）can support this feature

[MJD]

Hi @joanxie ,

Thank you for your information.

Can you suggest me please, exactly which Bluetooth module supports this features for IMX8m Plus? (playback audio on two Bluetooth devices in the same time)

[joanxie]

you can check this module

[MJD]

Hello @joanxie 

Is there way, that can we make output audio to play simultaneously one from headphone jack (Earphone plugin)given on the Imx8m evk and another from Bluetooth paired (Bluetooth earphones) devices from single source (audio).

If there is way, please guide.

Because in my yocto build image(imx-image-full), pulseaudio doesn't contain module-combine-sink even though i have updated version of pusleaudio 16.1, Detail's below,

[joanxie]

I suggest that you can create a new thread for this feature request, and put them to the wireless group, not imx group, attach your detailed request, they will give you more detailed answer for how to support such feature, because current bsp doesn't support this, you need double confirm from them,
