Xperia 1V not passing sound to hearing aids

[TheCustomer]

I'm struggling to get Xperia 1V to pass call audio and stream music to my hearing aids
(Oticon mini rite)

The phone can do this - I've had it working after a series of pairing/unpairing/repairing. But I can't say what I did to get it working other than turn it on & off several times.
I then lost the ability when I'd connected by USB-C to a different sound output, my car, which was recognised as a headset.
The phone didn't revert to the previous working audio streaming setup after I disconnected from the car.

But it still detects and automatically connects to my hearing aids, and defaults calls to Bluetooth, which I then can't hear.
I've just switched from a Google Pixel, where the sound worked faultlessly, so stock Android 14 doesn't have these issues.

Any ideas on how to fix this?

What can I do to set

@hehduda What did they advise you when you contacted them? Did they offer any troubleshooting steps or to send it to repair or what?

I have not contacted Sony.
I received my hearing aids at the end of March/beginning of April and tried to isolate the problem; Settings of the hearing aids, the devices themselves or the phone.
When I found this thread and read @TheCustomer 's report about his contact with Sony Support, I found it pointless to contact Sony.

Note: There was a mistake in my second post: of course I meant the manual for the Xperia 1V.

@hehduda I understand your point of view, but I'll have to disagree that contacting the Support line will not help! If they couldn't help, they will be directing you to the place that will. You'll also need to confirm the compatibility of the devices. 

Plus, it's a no harm action if they managed to fix the issue, you have joy.

@TheRealOG I didn't say that Sony support doesn't help. But saying they couldn't do anything because the device wasn't a European model. It wasn't even about the actual problem, but about sending it in for repair (and I don't think it's a hardware problem). Not very encouraging to turn to Sony (especially in this case).

No harm? But time intensive, you ask for help and wait a day, Then the answer is like: Is the software up to date and have you restarted the device? and a link to the manual.
Only then can you start solving the problem.
I know it's the nature of things and the answers take time, but it's nerve-wracking, especially when there's an error where there shouldn't be an error. Sony itself claims that its smartphones support the ASHA protocol.

[TheCustomer]

Indeed

If Sony Support were *trying to help* they'd have asked me some real
questions, like:
... Do I have the same issue with other audio devices (yes)
... with other hearing aids ( I have a set I could test)
... And failing all else, offer to send them my phone, and forward it to a
contact at the local market where I bought the phone

Instead I was met with intransigence 😞

@hehduda If the device is a non-European device, it would be hard to ensure the functionality on a European ground, cause while manufacturing any device the developers take into consideration the regional measurements for the country they manufacture on or for! 

But for the ASHA protocol was that claimed on ads by Sony, or did you get a confirmation from them directly on that matter?

I found this on a Sony website while searching for information on the subject in order to participate in this thread. I can no longer find this page, but Sony claims in the specifications of the Xperia 1 V and 1 VI (under Accessibility) that both devices are compatible with hearing aids (HAC). Some Sony sites lead me to GARI where I found that no ASHA protocol information is available for the Xperia 1V, but the 1VI is ASHA capable.

The specifications are e.g. for the Sony Xperia 1V 256 GB. Sony doesn't differ between the regions, so there is a lack of information?

On the other hand, if I understand your saying correctly: I'm going abroad with my XQ-DQ54, lets say to Singapore, my connection to my hearing aids (or headphones) will possibly not work?

By the way a late merry christmas and a happy new year to all!
