Audio limit? (latest version)

Unread post by pointjg » Tue Dec 15, 2015 8:20 am

Hi guys,

I've noticed that on the XU4 the volume can only be set at 60% (or 66%). In settings->sound if you adjust the volume it will go to 100%, however when you goto adjust it again it will only be at 60%.

I'm guessing this is the EU Limit in certain Android phones. Is there a way to defeat this? I've tried a few settings in build.prop, nut no luck.

Of note: this did not happen on any of my U3s.

Thanks,
J

I get a popup dialogue to acknowledge the risk of high-volume listening when setting the master volume above 60%. Trying to increase the volume on an application level without accepting this dialogue on an OS level always results in no change.
It took a few tries to figure this out back when my XU4 first arrived.
I don't know if this is the same thing you're talking about...

Hi HRRutz,

I haven't received the dialog warning. I figured it was missing from the image. Is anyone of aware of a way to reset the dialog warning?

Do you mean the audio limit of HDMI sound?
Which version of Android OS image do you use?

Yep, the audio is going out over HDMI and is limited. I've tested this on 2015-Nov-25 Android 4.4.4 (v3.2) (fresh EMMC image), along with the previous version.

The simple way to reproduce it is: go into settings -> sound -> volumes and adjust the top slider to the max volume. Hit ok and go back into volumes - it will be at 60% (or 66%) instead of 100%.

I've tried testing different versions and haven't gotten anywhere. The U3s did not have this issue. Can you please help and point me in the proper direction?

We still couldn't find which source code causes the volume limit. :( It's very weird.

Does the same problem happen in the Lollipop (5.x) or Marshmallow (6.x) images on the XU4?

It Android 4.4.4 v. 3.4 (I think). I am using what was installed on the eMMC I got with my XU4 a couple of weeks ago. In About, it shows: Build number odroidxu3-eng 4.4.4 KTU84Q eng.jenkins,20151125.111037 test-keys

Still trying to figure this out (have not tested Android 5 or newer images, need to stick with 4.x for now).

Supposedly in 4.4.4 there is supposed to be a "safe headphone volume" checkbox in Settings -> Sounds -> Volumes

There are Xposed and Gravitybox mods that are supposed to set config_safe_media_volume_enabled to false, but in testing the Xposed mod it did not work.

Edit: also found this from http://forum.xda-developers.com/showthr ... 069&page=5

Code: Select all

- framework-res.apk/res/values/integers.xml YOU MUST USE NOTEPAD++ DO NOT USE MS NOTEPAD (Linux users need not worry)
- Find the following "<integer name="config_safe_media_volume_index">10</integer>"
- Change the "10" to a "20"

Hi odroid,

Thanks for addressing that - however the safe-volume-limiter is reset on reboot. Any thoughts?

Thank you codewalker. Is there an ETA on the next release? (we've been testing newer versions of Android, along with CM setups, but run into issues that have us focusing on 4.4.2)
