The same problem, low-quality sound, loud-speakers hiss and crack. It is necessary to write in support, the more appeals, the sooner they will pay attention to this problem and correct
You can disable Dolby as a temporary workaround.
disabling Dolby does not help, the problem remains
Try restart and use the phone in safe mode, just to rule out any third-party app interfering with the sound:
In the shutdown menu > press and hold restart > select restart in safe mode.
Do another restart to get back to normal.
Notice: You may have to set up third-party widgets again.
If the loudspeaker is still malfunctioning, backup everything and do a factory reset before having the phone inspected by a technician.
- Rolling back to a previous OS version is not an option, officially.
The Dolby surround feature got too much gain/pre-amplification with the Oreo update, especially in Theatre mode.
For example, lets say a comfortable audio level in a pair of 16 Ohm wired headphones without Dolby is 80% on the volume slider, I need to slide it down to 50% in Dolby surround Music mode, and to 30% in Theatre mode.
The advantage is that videos with quiet audio now go full blast with Dolby Theatre mode enabled. It's just too much!
(I welcome the louder maximum output in wired headsets on Oreo without Dolby).
All these manipulations do not help. Would have been a specialist nearby, would have long ago turned. The problem is that the service center is very far away. Sending and returning the phone will take at least a month. Give a new phone so that someone digs around it is not a good option. Before giving for repair, there should be a possibility of rollback to Adroid 7.2.1. Please do not hesitate to roll back to the previous version. People should have a choice.
The audio output from both loudspeakers in Nokia 6 must be clean without Dolby, in Oreo too.
FWIW without Dolby and with the volume sliders at 50% instead of 80%, the output is my preferred volume and clean on a TA-1021.
When disabling Dolby does not help I suspect a mechanical failure.
Proper assessment and repair cannot be done over the Internet.
Please consult a technician for a hands-on evaluation, or wait and see if a future system update makes a difference.
This problem needs a quick fix. The volume is too loud. This applies to the alarm and ringtone, the volume scale is screwed, the 1st level is loud already. For some reason the media volume scale is working, i.e. when playing an Youtube video the volume control works fine.
Same issue here on two Nokia 6 devices model TA1021. I was on the support chat and the employee wasn't aware of any known errors. Well lets hope it will be fixed soon, taking your phone in a public space could get embarrassing when not completely muted.
The Android 5.22A/February security update have resolved the volume and Dolby Atmos issues on my TA-1021. It's a 1,7GB bundle, again...
Same problem here, even the lowest setting was way too loud to listen to podcasts in bed. Deactivating Dolby seems to have worked. I have not yet received the february update.
