Tuning System Wide Volume Level

---

As I making a beats mod for sense 3.5, found interesting file TPA2051_CFG.csv and TPA2051_CFG_XC.csv, the first one should be the template and the second one is the working i2c command file for various system volume, search google for TPA2051, is the amplifier which uses i2c interface, I don't know what exactly i2c is, maybe electronic engineers can explain. Comparing XE and normal sensation's, giving only one difference value, see below in blue, that is the playback_headset max amplified value, XE is 55, sensation is 50, that's why the later you hear a lower volume, tweak it to 56 or maybe higher to here boom-boom-boom, pong-pong-pong, ping-ping-ping effect!

For ICS, get the files from my beats mod.

Do not tweak other values except you know exactly what you are doing, there are many of them are gain control, just one bit of them could doubled the gain and may damage your speaker. The datasheet has all the descriptions of these registers of I2C interface.

0x55 seems to be the largest value that the stock htc headset and beats headset can tolerate, 0x59 seems to be the largest value that the speaker can tolerate. For both, the largest volume value is 0x5F.

This should also applies to any other htc devices as long as there is a file similar to this, this is sensation's TPA2051_CFG_XC.csvf ile, if you are using other device, just use that file of your device.

================================================
SoundBoostForGB&ICS.zip
This work for both GB & ICS, without enable the AGC, enabling AGC making music sounds not so good, values for headset is default of XE ROM (0x55), and speaker is (0x59)

i2c is a in-circuit protocol for comunicating. Thats the protocol the chips and memory banks use to transfer and address data. It is based on a serial connection. I dont know if any of that helps but just wanted to share that info. Now for a question, how to apply and what are the compatable ROMs?

A big thank for your information, and that proves that value is the radio button of amplifier, and since it is a protocol, it will alike for all devices that uses the same chip, how to apply I'll post it on first post. Thanks.

Hi,
I just tested for the value in PLAYBACK_SPKR,set as you recommended and...Yes it works!There is an improvement
Thank you very much for this tip,very good
No one else has tested

WELL DONE. It works !!!! I will look into the other files and see how to tweak them if and when I get time because I'm at college for my masters all day. If there's anything I can help you, feel free to PM.

senastoin xe sense 3

would this work on my sesation xe runing sense 3 stock rom and were do i fiid the files new to this first andriod phone was using wm6.5

it should work, didnt check it but it has ti have this cofig file. It says in the first post, I used ES file manager, and enabled the root access feature and browsed to the file specified and chenged the 2 values.

I found the AIC3254_reg_dualmiccx file and after a loooong review of the datasheet from texas instruments, it seems that the video recording clipping can also be fixed this way. I found that in the:
A17,VideoRecord_IMIC,SET,w,w,w,w,w,w,w,w,w,w,w,w,w ,w,w,w,w,w
,,REGISTER,0x00,0x34,0x36,0x37,0x39,0x3B,0x3C,0x00 ,0x51,0x52,0x53,0x54,0x00,0x0E,0x0F,0x09,0x12,0x13
,,VALUE,0x01,0x20,0x02,0x20,0x02,0x58,0x58,0x00,0x 00,0x88,0x00,0x00,0x01,0x02,0x02,0x3F,0x03,0x03

you can change 83 and 84 memory bank (0x53 and 0x54) to control the volume. 0000 0000 is default in the datasheet, which is 0dB.To lower the gain you have to write a negative digital number in those registers eg. 1111 1111 is a gain of -0dB.

Thank you celelivada, I'll try at weekend. One more question, I,m tweaking some soundimage file for sound effects, the srs processor, there is input & output gain, default is 1.0 in and 1.0 out, the question is if input tweak to 0.5, will I get a a louder out?

Works great, thanks for the tip ...

nice. cant believe a volume fix was that easy and i know its been an issue for a long time.
