This is not strictly a Linux-issue as I reproduce this issue under Windows 10 as well (but can not reproduce under Android or macOS), but I will be using Linux for any troubleshooting and I wasn’t sure where else to post this.

I have a pair of Sony WH1000MX5 that acts like an expensive piece of garbage so far. I will eventually (usually within 2-10 minutes usually) hear crackling noises when using the headset via Bluetooth in high-fidelity mode on my Linux machine (and as mentioned above, this is reproduced on two other machines running Windows 10). The crackling noises are there regardless of whether active noise canceling is active or not. It is not constant, but it is enough to significantly reduce the listening experience, especially for tracks where not too much is going on, such as quiet piano pieces.

On my Linux machine, I can choose between three codecs: SBC, SBC-XQ and LDAC. It tends to be less pronounced using the LDAC codec over SBC (right now I’ve had a longer period with no issue). SBC-XQ also seems better. However, I have experienced it for all choices of codecs before. Also, under Windows (which I must use for work), this does not seem to be a choice at all. But I wonder if the problem lies here? I don’t know much about Bluetooth codecs.

Ideally, as in addition to these issues, they are not very comfortable, I would like to return them and get a refund (should be possible under local laws), but I am having some issues with the retailer claiming they can’t find anything wrong with them after two trips to a repair shop. The first time they factory reset it and updated the firmware, the second time they did nothing. I don’t think local Sony support will be of much help, and the local laws relate to to the buyer/seller contract, so for the refund or repair they will anyway refer me to the retailer.

So I am trying to get a better understanding of the issue before pursuing this further, and if I fail to get a refund, I would like to fix the issue if possible. So if anyone is familiar with this and could help point me in the right directions to fix these issues, I would be very grateful.

    You have pipewire. It is compatible with pulseaudio. I find it very surprising that you don’t show aac. I am not familiar with sbc-xq, but Apple products don’t support ldac and my understanding is sdc is not useful for audio listening, but rather calls. My M4s work fine on my desktop with an intel ax201 Bluetooth chipset. I have been using aac there, but ldac worked I think. I had problems with the usb BT adapter before that though.

      Hm, yeah. Just checked in macOS, and it is using AAC there. So lack of AAC on my Linux device would mean it is not available here for some reason then I guess, and not an issue with the headset?

      I can’t seem find a way to check the same on Windows 10 without using a third-party tool, and since this is a work computer, that is not an option for me. My guess is then that it uses SDC. Seems like AAC is supported natively in Windows 11 though, and the device is scheduled for a Win 11 install soon. Hopefully that will resolve the issue for me during work hours.

      For now it seems to work better under Linux with LDAC though, which is my main use case. I swear I’ve had issues with this before, but I just streamed an entire album of high-bitrate FLAC tracks without issue now. Hopefully it stays this way.

        I would assume either the way it was packaged for your system or some missing package.

        Don’t you love when you give in and go to get help for something and you can no longer reproduce it after you ask?

          It’s almost like it’s a law of nature…
