OK, thanks @Zebras for clarifying that you know what I meant but still insisted that your audi told you it can nevertheless still be done via making the volume adjustment in the Phone section, despite this seemingly to be a ConnectClip issue.
I thought that it was interesting enough to be worth checking it out for myself. So I tested it with my ConnectClip connected to a Samsung Note 8 that I have (a pretty old Android phone with no ASHA support there). And lo and behold, what your audi told you is indeed correct. I could get my Samsung Note 8 to sound louder through the ConnectClip if I increased the volume on the Phone Loudness (as seen in the screenshot below) for the Phone section. I tried both the minimum value and maximum value of the Phone Loudness and confirmed that it makes a difference both ways.
Thank you for pointing this out, @Zebras ! I didn’t think it would work because my aids are not connected at all to the Samsung Note 8, except via the ConnectClip to the Note 8 through Bluetooth. I’ve always assumed that the Phone section in Genie 2 is for direct connection between the aids and the phone only, but apparently Oticon made an exception and let you use the Phone Loudness in the Phone section for the ConnectClip streaming.
What Oticon should have done to avoid the confusion is to add a Device Loudness parameter inside the ConnectClip itself (in addition to the Remote Mic Loudness) so that the device the ConnectClip is BT-connected to (laptop or Android phones or non-Apple tablets or whatever) can have its volume be adjustable right there in the ConnectClip window, which should be a more appropriate location for it.
So @SpudGunner , I take back what I told you earlier, Jim, that it can’t be done, because @Zebras has proven me wrong. Now you can ask your audi to make that adjustment for you to make the phone sound louder through the ConnectClip.
