Volume Warning for headphones missing.

[mekanix]

Xperia Z5 compact.

The warning that usually comes when you try to turn up the volumen to high, have suddenly disappeared from my phone. Don't recall that I have disabled this.

Also, separate volume control for headpone (wired) and bluetooth are missing (don't remember if they have been missing all the time or if that is a feature for Lollipop).

How do I get that warning back?

I realize that this is a very late reply but i just got some more information on this.

The European standard EN 50332-2 specifies the sound level limits for combinations of headphones and personal music players (PMOs) such as smartphones or tablets. Some of the features of EN 50332-2 are:

• The maximum output from the PMP and headphones must not be greater than 100 dB.
• The user must be actively warned if the sound pressure level exceeds 85 dB for more than 20 hours per week. On Xperia™ devices, a pop-up warning will appear on the screen.

The safety caution can't be turned off, and it does not affect connected Bluetooth® accessories.

The sensitivity of the headphones will have a large influence of the sound level. The higher the sensitivity of the headphones, the louder they will play for the same input voltage. This means that for the same input level, different headphones may or may not provoke the pop-up sound level warning.

Note! The safety caution may not be shown in all Xperia™ devices since it's market or region dependent.

Hi Rickard / Sony Xperia Support

Thank you, finally someone that can actually answer why this extremely annoying "feature" is present on all Android devices. And from what you write it seems the warning cannot be disabled due to legal regulations, so I guess we'll have to live with that.

BUT the fact that there has to be a WARNING does not mean the phone should have to lower the volume by about 50%, which is the real problem. Fine, let there be a warning notification but PLEASE make it possible to disable the automatic volume reduction. This could be an option in the sound settings. I know a lot of people would be very happy about this improvement, there are hundreds of threads on this on the internet if you google...

For me personally, this is a big issue. I use my Xperia many times a week to play music for my exercise sessions and without using maximum or almost maximum volume, the sound signal effect on the headphone jack is not strong enough for the sound to be loud enough (this goes for a big variety of PA amplifiers I have used). Which means I need to use a high volume.

On random occasions throughout the years this has led to the sound suddenly disappearing almost entirely when I'm instructing in front of 50+ people and I have to run to the phone and fix it. As you may understand, this is beyond annoying - it affects the quality of my instructions and sessions, also it's very unprofessional. I have tried using applications that claim to "fix" this warning, but none of them (inlcuding the Hearing Saver) work perfectly - the sound still disappears sometimes.

It's a real problem that has led me to consider not using Android devices for this purpose - and since the media player app my training club uses is Android or iOS only it would mean switching to an Apple device. And I really loathe Apple... I DO NOT WANT to use an iXYZ device. And I also feel Sony is way better than most other Android-based devices, much more stable and less bloated. So I would prefer to keep using my beloved z5c (best phone ever).

Thus, I would really appreciate if you could feed back to the Sony Android dev team that making it possible to disable the automatic volume reduction as an option would be very much appreciated - by me and by others.

Praying this will happen... /Dan

@DanLilliehorn This can't be done:

http://www.isvr.co.uk/labtests/en50332.htm

At volume settings for which the output voltage is greater than 27 mV, the user must be informed by a visual or audible signal, *and must acknowledge the signal, before he or she can override the volume limit to allow replay at these settings*. The warning has to acknowleged at regular  intervals. The equipment must default to a setting which gives 27 mV or less when switched on.

This means the volume has to be turned down.

It depends on the volume and what output (bluetooth, aux, headphones) you use. But yes, after playing music for 20h with headphones/eraphones at a volume of above 85dB you will get the warning again.

These warnings can't be turned off so it's not a setting you've changed.

Reread the first line again... aux ... which connection does that go through... the jack? If so, is android able to tell the difference between headphones and loudspeakers?

Anyway - last year I had the phoned attached to a speaker-system for several days and one day the warning just popped up. But haven't really seen much to it since. So those 20h might be it. 

I do miss the instant warning when you turn the volume up to loud.
