Call problem with Cyanogenmod 12

I have HTC 816 Dual SIM indian Variant and i have flashed the CM12 Dated :2015-04-26 11:35:05
I am having 2 specific problems and they are :
1. Audio from the speakers are cracking when a song is being played on full or 90% volume..
2. Whenever i put one sim on 2g and one sim on 3g, calls are possible from the 3g sim only. From the 2g sim if i try to call or receive a call neither the speaker works nor the Mic. Even if i reverse the 3g/2g mode the 2g doesnt seem to work.
If you have a solution please help me out! Thank you..

This is not an Active Dual-Sim phone, so you can't because the hardware doesn't exist on the device, but you can always use smart forward which automatically forwards your other sim to your online one

How does smart forward work ?
Was under the impression that forwarding had to be set up with the ISP as the phone does not even know when an incoming call on the other sim arrives or am i wrong.

enable smart forwarding in your phone.. it will atleast show "callwaiting" to your caller when you're already in a call

Dual Sim issue

Hi
I have an issue with my dual sim S9. Sim one is on Three UK and sim two is Vodafone UK. " Dual sim always on " is enabled but when I'm connected on a call the other sim card will not accept incoming calls. The sim I'm connected to for the call will show via call waiting if another incoming call is waiting but only for that sim card. It effectively means that the other sim is offline until I end my call. Being my first dual sim phone I thought I'd be able to be notified about incoming calls on both sim cards at the same time (if I'm on sim1 and a call comes in on sim2 for example)?
The other issue I have is that the Three sim is personal and the Vodafone sim is work. When dual sim is enabled it automatically forwards calls from sim1 to sims2 and vice versa when the phone is unreachable. This means personal contacts end up leaving messages on my work voicemail and work customers end up getting through to my personal sim. (I'm also assuming my network will be charging me to forward calls to the other network)
If this is how it works then I'll have to go back to two phones as I can't mix personal and work calls like that.
Thanks.

Me also i go this problem.. This is a very FAKE DUal SIM ! it does not receive all on both sim at the same time. Huawei p20 pro receive call at the same time
