Have you installed ffmpeg?
Except SBC, aptX, AAC, your device also supports "Vendor Specific Codec ID 0x0025" -> aptX HD and other unknown codecs.

[jaccc]

It doesn't support aptX HD according to Haylou and Qualcomm pages.
aptX HD should be 0x0024.

0x0104 - The CSR True Wireless Stereo v3 Codec ID for AAC

[EHfive]

Oh, yes. Seems those are aptX Adaptive and Qualcomm ANC (Adaptive).

So you want support of those codecs?
Without any spec or en/decoder of those, it's not possible to achieve it.
