Sound promblems fixing

If You faced the problem that the sound goes from rear dynamic of the phone but not from the one near Your ear, or there are some other problems with the sound, it seems to be connected with the drivers of Your phone.

There is a common method how to fix this problem.

To do that change to Expert mode in common settings of the phone, try to make experiments with the next settings (in section Multimedia):

  • Use Mode audio API (at first try only this option)
  • Use API routing
  • Tone hack
  • Use WebRTC implementation
  • Micro source
  • Audio mode for SIP calls

Try each of this parameters separately, and then try to combine. If one or combination of parameters helps ... then good news for You, Zadarma program works correctly on Your phone;). Then You can share it with us which parameter helps, in order we could make it by default for given device.

Also it's possible, that none of these parameters will help (for example, there is a problem with some Samsung models). In that case all we can do is to hope that the manufacturer will fix this problem in new drivers update. Perhaps, it will be possible for Your phone to choose another special option, but it requires skills of developer and the phone for testing. If You faced such case, You can contact us, and we will show You what is needed to be tested in source code to fix the problem.
