Hi,
Everybody know problem of recording during live concerts.
That is impossible to grab properly level of sound because is to loud and sound is very crap.
I think I found solution. Needs use Hidden Menu.
3845#*760# (for ported ICS from SU760)
3845#*920# (for p920)
Hidden Menu
Device Test > H/W Test Menu > Sound Test > Audio CAL Tool > SetGain > (Device Type)sub mic > AMIC 110 (decrease from 120 to 110)
Device Test > H/W Test Menu > Sound Test > Audio CAL Tool > SetGain > (Device Type)sub mic > D_MIC 110 (decrease from 149 to 110)

For P920 v30A

After reboot this settings will be reset.
I did try on concert:
1. Bad sound:

Unfortunately, com.lge.hiddenmenu has stopped

can someone explain to me exactly. have I flashed kernel but here I can not get further
Please note that listening to too high volume music over 1 hour can damage your ears.
Or makes your speaker/headset overload.
( 5.0+) Sound control has been enhanced.
( 5.1+) Sound control behaviours have been optimized.
Switch to sound control folder first:
cd /sys/mo*/snd_soc*/p*
* Use RootExplorer to view this folder,you will see a lot files.
Sound hacks wont take effects immediately.It depends on powering on/off ab8500 asoc.
Stop music for 5s to let ab8500 asoc shut down fully,then turn on music.
You need to enable XXXXX_con first,then tweak the XXXXX_bit.
After enabling XXXXX_con,it will be applied when codec powers on or it wont.
How do i check whether it has shuted down or not?
dmesg | grep codec
If you get "Disable ab850x",it has been powered off.
I will explain how to calculate the binay values below.
If we echo 0000 to something,system will consider it as 0.
But that doesnt matter.
'(default)' means that is my default setting in sound control.
[AnaGain3] (Headset audio path):
Ana stands for 'analong'.This is analong gain.
To enable control:
Quote:
echo 1 > anagain3_con
To tweak volume: [volume 0(default, +31dB) > 34 > 68(stock) > 85 > 87]
Quote:
echo 0 > anagain3_bit
* Most values(except 0,34,68,85) will make the volume lost balance.
* If you hear too much noise with 0,34 is recommended.
* It is nice to use 0 with large speakers(audio output)
[HsXDigGain] (Headset Digital Gain)
HsL means left channel.HsR is the right.
To enable control:
Quote:
echo 1 > hsldiggain_con
echo 1 > hsrdiggain_con
To tweak:
* 0000: +8 dB gain (default)
* 0001: +7 dB gain
* ....: -1 dB step
* 0111: +1 dB gain
* 1000: 0 dB gain
* 1001 to 1111: -inf dB gain (mute)
Quote:
echo 0000 > hsldiggain_bit
echo 0000 > hsrdiggain_bit
* If you use +31 dB AnaGain3 + +8 dB DigGain,the result will higher than +39dB!
* Be careful,when the volume is too high,codec will power off automatically.
* Experience the differences between digital gain and analong gain by yourself.
[HsLowPow] (Headset low power mode)
This lowpow mode is enabled by driver normally.
If you want high performance audio instead of LPA(low power audio),
You can disable it.
To enable control:
Quote:
echo 1 > hslowpow_con
To tweak:
* 0: Normal Operation (default)
* 1: Hs drivers in Low Power
Quote:
echo 0 > hslowpow_bit
[HsDacLowPow] (Headset DAC low power mode)
DAC is Digital-to-Analong Converter.
This lowpow mode is enabled by driver normally.
To enable control:
Quote:
echo 1 > hsdaclowpow_con
To tweak:
* 00: Normal Operation (default)
* 01: Hs DAC drivers in Low Power
* 10: Hs DAC in Low Power
* 11: Hs DAC and Hs DAC drivers in Low Power
Quote:
echo 00 > hsdaclowpow_bit
[HsHP] (Headset high pass filter)
This high pass filter is disabled by driver normally.
Enable this can reduce some sub-nosie of audio.
To enable control:
Quote:
echo 1 > hshp_con
To tweak:
* 0: Headset high pass filter disabled
* 1: Headset high pass filter enabled (offset cancellation enabled) (defualt)
Quote:
echo 1 > hshp_bit
[ClassDDithHPGain]
ClassD is a kind of amplifier.
According to the documents,our ClassDs only relate to Handsfree(speaker).
To enable control:
Quote:
echo 1 > classdhp_con
To tweak:
* Gain control for the high pass component of dithering filter
* 0000: Minimum gain
* ....:
* 1010: Maximum gain (default)
Quote:
echo 1010 > classdhp_bit
[ClassDDithWGain]
* Gain control for the white component of dithering filter
* 0000: Minimum gain
* ......:
* 1010: Maximum gain
Quote:
echo 1 > classdwg_con
echo 1010 > classdwg_con
[ClassDHiVol]
This is a gain of speaker.But +2dB only.
echo 1 > classdhivol_con
Say 1(default) to enable:
Quote:
echo 1 > classdhivolhfl_bit
echo 1 > classdhivolhfr_bit
* In fact,our speaker is right channel only!
[ADDigGain2]
This is the audio path of mic2
Quote:
echo 1 > addiggain2_con
Quote:
echo 9 > addiggain2_bit
* Default: about +20dB
* Max: Say 0 to addiggain2_bit to +31dB
[EarDigGainb]
This is the digtal gain of earpiece
Experimental still.But you can try.
Quote:
echo 1 > eardiggain_con
Quote:
echo 0 > eardiggain_bit
* The values of eardiggain_bit is the same as hsldiggain_bit
How to calculate the binary values?
We use HsXDigGain as example.
The gain step is "+1".
In binary: So the values will like these:
0+1 = 1 | 0001: +7 dB
1+1 = 10 | 0010: +6 dB
10+1 = 11 | 0011: +5 dB
11+1 = 100 | 0100: +4 dB
..... | ......
[Experts!]:
This method can work on any ab850x codec platform!
Quote:
cd /d/asoc/U*/ab*
Play music,reduce the volume.
Now we are going to edit the codec registers.
Quote:
echo REG VAL > codec_reg
E.G:
AnaGain3:
Quote:
echo 0x16 0x00 > codec_reg
HsDigGain: (left/right channel)
Quote:
echo 0x4F 0x00 > codec_reg
echo 0x50 0x00 > codec_reg
Disable all lowpow mode:
Quote:
echo 0x04 0x00 > codec_reg
* These hacks will restore when codec power off.
Can you please highlight your Question in BOLD and use the
code for the rest of the quoted information...
and yeah, if you want to Increase your Stock Volume limit, then try the easy way, use this app instead... but it might be risky to use the mod to go beyond the limit - as it will affect your phone's speaker.. you will get hardware problems in the future...

I found this old app still works great on my D802 QB2 with this (HEADSET) setting:
1. Audio Modifications = Enabled
2. Simple Volume Boost = Disable
3. Bass Boost = 8 (max)
4. Echo/Delay = 0
5. EQ Preset = Bass Boost (or others) just make sure to set "Volume Level" to 0
SPEAKER setting only work with this:
1 - 4 same as headset
5. EQ Preset = Flat & "Volume Level" set to 10
need to enable/disable eq preset till this work
BLUETOOTH setting: untested
Nice, but the phone already kills my ears on full volume! (Headphones)
That app was awesome back in the day. Before Viper4android

Hey,
Can you share your car audio profiles?
Recently I have Viper4Android and I do not understand many settings. I know it's often a matter of taste and audio equipment, but maybe there will be some nice setup.
Finally, the question is, is it possible to make Viper4Android work for FM radio as well? Are all the settings that will work only in the phone speaker tab?

Hi, how did you installed it?
I've tried it with the magisk Apps, but the Status in Viper ist Unnormal/Abnormal. So i can't really change a lot of settings. Also the App doesn't start automatically after reboot.
Is there a way to install Apps/Mods with Magisk, where the program need me to touch a Volume Buttons? If i push one of the Buttons, the System doesn't recognize it.

Android version?
If 10+, for install, you'll have to install selinux permissive script for Magisk, than after reboot, simply download v4a.apk (not magisk module) and install it. Start it, allow to install driver, auto-reboot, profit.
If still not working - check "legacy mode" in v4a settings. Should work.
*OP 7T PRO McLaren, i trying a few ways to install v4a as magisk module, trying different patches, fixes in various combinations. Finally, download .apk separately, it work.
