Audio issues on the iPhone 7 are quite common. While this may appear to be iOS related, it is probably a hardware issue. This can happen seemingly out of nowhere and usually follows a reboot of an affected device, like when you shut it down to repair it or update it. Sometimes the removal of the screen gives the logic board that last “flex” that puts it over the edge. Once rebooted, the phone exhibits symptoms that were never present before.
The iPhone 7 series of devices have proven to be very unreliable, suffering from flex-based issues similar to the iPhone 6 Plus (Touch Disease). On the iPhone 7, the fault line runs along the top of the SIM card reader and affects the Baseband CPU and Audio IC. Any short copper traces running perpendicular to the fault line while connecting to micro-BGA pads, is subject to failing.
On the Audio IC, this particularly affects the C12 pad/trace although there are 4 pads/traces along the fault line. Of those four, the C12 pad (I2S_AP_TO_CODEC_MCLK) is the most critical as it is a communication protocol line between the CPU and the Audio IC.
Here are the typical symptoms, as collated by the repair community:
This is a repairable problem but it requires a micro-soldering repair. Although it can be a routine repair for an experienced tech, it can go sideways very quickly as the Audio IC is directly opposite the underfilled Baseband CPU. An unqualified tech can apply too much heat and cause massive problems. So do your due diligence.

iPhone 7 series iPhone have such speaker greyed issues is common. You can`t fix it with any software. Only the solution is the hardware that I also faced and solved this way. That is the only solution by hardware.
