libopenaptx VS pulseaudio-modules-bt

AptX Low-Latency support is possible with a software update or software mod, source: https://github.com/pali/libopenaptx/issues/1

Background: I use Tumbleweed for audio recording/production among other general use cases. This lead me to manually switch to pipewire before it was made the default recently. During my research before making the switch I learned that the pipewire packaged in openSUSE does not support aptx and AAC bluetooth codecs because dependencies libopenaptx (https://github.com/pali/libopenaptx) and fdk-aac (https://github.com/mstorsjo/fdk-aac) are missing. I believe LDAC support works despite it sometimes being referred to as "nonfree" due to libldac being packaged with openSUSE, but I have not confirmed this. Support for aptx is important to me so I installed the version from packman which is compiled with support for these codecs. However, this got me wondering if it is possible to provide aptx and AAC in openSUSE without needing to install it through packman.

probably ... dunno for sure, since there is libopenaptx : https://github.com/pali/libopenaptx

A 2 weeks ago i needed to install Linux Mint again because my SSD was broken. So everything is working now but the standard audio quality of SBC is poor. Also there is standard no AAC codec installed. So i installed the codecs with this instruction: https://github.com/EHfive/pulseaudio-modules-bt and the codecs are ok. But i don't know where to change the bitrate of SBC. I know that the audio quality increased when i changed manual some settings in a file. But don't know where and can't find any information anymore on Google about this.

Can’t speak much to video issues, but I found pulse audio helped a lot with my Thunderbolt/USB audio issues.

No sound with either codec. Purchased and asked them what's up. Fingers crossed. Really don't want to waste time with the VM and pulseaudio-modules-bt.

Try this instead: load-module module-bluetooth-discover a2dp_config="sbc_min_bp=34 sbc_max_bp=34 sbc_freq=44k sbc_cmode=dual sbc_alloc=auto sbc_sbands=auto sbc_blen=auto" If it works when you restart PulseAudio, try a higher bitpool value. avinfo should show if the connection to your device supports it, and the maximum value.

In the meantime for people who want AptX, AptX_HD or LDAC for PulseAudio 15 on Ubuntu 21.10, you can use the legacy EHFive modules that I've packaged up in my PPA: ppa:berglh/pulseaudio-a2dp. These modules do not include the updated and improved SBC_XQ codecs that are already available, if you want to use these more than AptX or LDAC, do not install the following modules.
