    Hi Axel

    That thread was something else and has since been updated in the firmware. We are having a hard time replicating your issue here. I would try powering down the C658, wait 5 minutes then power it up again and see if the problem persists. If it does, please select Help, Send Support Request so we may review the Player log file.

    I know this is marked as answered, but I have been experiencing the exact same issue on my unit since purchase. The lowest possible volume setting when set from an Apple device using airplay corresponds to -47.0db/28% on the C658. One notch lower on the airplaying device, the C658 mutes. At 50% on the C658, the airplaying device is at about 2/5ths on the volume slider. This has been tested to occur using multiple devices and multiple version of iOS and MacOS, including iPhone 11 Pro (13.5.1), iPhone 8 (13.6), 2013 Macbook Pro (10.15.2), 2019 Macbook Pro (10.15.6). This has occurred for as long as I've had the C658, which spans three versions of BluOS (3.8.13, 3.8.17 and 3.8.19).

    For me this is also still really unsatisfying!
    Even I understood the airplay limitation, it would be great to somehow be able to configure the range so that volume control makes sense again. Let’s the is a parameter of maximum internal AirPlay volume in the C658. The device could then adjust the steps from that and finally AirPlay can be used seamlessly.

    Please bring a solution for it.

    (In General a Maximum volume setting would be great to prevent speaker damage)

    Chris, here is the follow up case I created back then:

    Hi Axel

    Other's cannot see your interaction for privacy reasons, but I will be happy to share the great and detailed response by our level 2 support team at NAD. It is a volume scaling issue that our players have far more detailed volume control than your Apple device - our recommendation? Once you have started AirPlaying, switch over and use our volume control, not Apple's;

    Hello Axel,

    What you're noticing here is a limitation of the Apple volume slider in comparison to the volume slider used on our devices. The Apple volume slider has a maximum of 30 different volume levels, meaning there are 30 options or steps between full volume and mute. Each of these volume steps represents roughly 2dB of volume for a maximum of 60dB of volume swing using the 30 steps.

    In the C 658, your volume is able to go from -80dB up to +12dB which is a total of 92dB where the Apple volume slider can only handle 60dB total. It's this discrepancy that prevents the AirPlay volume from going lower. Counting from +12dB would have the volume go all the way down to -47dB on the C 658 before the last volume step which would be mute.

    I hope this helps clarify the behavior of your C 658. Please use the BluOS App for finer control of your volume.

    Should you need anything else, please don't hesitate to ask. We're here to help!

    Kind regards,

    That being said, our QA Team has passed this information on to Apple for review.

    Hi Tony,

     

    thanks for the reply and forwarding. Although using BluOS App is a possible solution, it is not a convenient one, since I would like to use the hardware volume controls on my iPhone / iPad. What speaks against a customizable min max volume range in BluOS?
