        Hi!

        I have a problem with my Bluetooth helmet headset (Cardo Freecom 1+) using with VollaX23, it pairs fine and I am able to stream audio, but there is no sound or mic input when making calls. Unit works fine with android phone, also other bluetooth headsets work fine during calls.

        Here is dbus log:

        It seems like to switch correctly to HSP and when receiving calls the headset sounds incoming call sound. But when call is answered there is no sound, I can switch to phone or even speaker and it works fine, only the headset seems to be muted during calls.

        Pulseaudio log displays only

        library "libsndcardparser.so" not found.

        Thanks in advance and any help is greatly appreciated.

            Me, too. I have tried two different headsets.

            Is this a known problem?

            OnePlus Nord N10 5G
            UT 24.04-1.x daily

            TIA

              Hi,
              I have a slightly different problem.
              Oneplus Nord N100 (UT 24.04-1.2 stable) with Nissan hands-free kit <MyCar>. Pairing works without any errors, but the screen shows that no network is available. This means that I cannot make or receive calls.

              It seems that my hands-free kit cannot handle VoLTE, is that correct? šŸ¤”

              With UT 20.04 OTA 9 / on the 3G network, it was possible to make calls using the hands-free system. šŸ‘Œ

              šŸ“± Oneplus Nord N100 UT24.04-1.2 stable; then Xperia X (since 2020) at last UT 24.04-1.2 RC, now out of service due to defective camera
