[Q] In Call Volume

I still have the stock OS .....2.3.4.... I did root it but did not unlock the bootloader. I don't remember when it started happening but after I rooted it sometime. I rooted it via the One-Click Root script. Anyhow, when I call someone, the ringing is low volume, but after the person picks up the volume increases to normal. The ringing is so low that I can't even tell if it is ringing when I am driving. Anyone have any solutions. I have tried pressing the volume on the side of the phone but no luck

[Q] How to ENABLE beep when phone is plugged?

Hello all;
I swear I searched for this but I could only find questions and answers for the opposite problem - how to stop the phone from beeping when plugged.
I upgraded my Samsung S I9000 from stock ROM Gingerbread to Cyanogen 10 (Android ICS).
The phone used to beep when plugged and now it does not anymore. Having I sight issues that audio clue was helpful.
I cannot find how to enable it back. Is it possible, and if so please how?
Many thanks!

You can set an event to satisfy your needs. I've set 3 separate sounds for when my phone is plugged, unplugged and fully charged.

[Q] Ringtone sound real low after lock up and reset

I am running Cyanogenmod 10.2 current nightly.
I was talking in my car on bluetooth and the phone locked up.
I pulled the battery and it reset and all that came up was the galaxy s4 logo.
I did a second battery pull and it loaded correctly, but sound from the speaker when a ringtone/notification goes off is very low.
Is there any way to fix this.
I have since done two nightly upgrades since this started and it did not fix the problem..

Removing audio service

Hi I have an old Meizu MX4 phone that is experiencing this issue of it ghost adjusting the volume on its own. My phone is rooted and i was wondering if i could somehow completely disable the audio service completely in Android in order to prevent the phone from adjusting itself on its own. Any suggestions?
