Hi @Timespansoul
I have restarted the phone several times and I have also tried to switch to speaker during calls.

@MrT10001

After some reboots, the second sim is available.
However, when I have this sim inactive ( not using PIN to unlock), I'm not able to use the Cellular data on the primary sim.
Although data seems active, I have no internet at all ( route table is empty!).
If I reactivate the second sim, then cellular data on the primary sim is working.

Has anyone experienced this before?

@MrT10001

thank you for the instructions.
I managed to installed the required OxygenOS image using the MSM tool and there is now audio in calls! Thank you all!

A problem I'm facing now is that the second sim ( I have two SIMs inserted) is not visible at all. I thought that only the cellular data is not working on the second SIM in this phone with UT.

Is there any way to have the second SIM working ?

thank you

@AppLee

thank you for the detailed explanation.

I have tested stable, rc and finally devel but with all channels I still have no sound in calls. The interesting part is that if I press some numbers in the dialpad during a call, this sound is transfered to the caller.

I have also tried to reinstall UT 20.04 stable using the ubports installer but I still have the same issue.

Before installing UT, I had installed oxygen 10.5.2 (BE83BA) by downloading the OTA image and doing a local upgrade. I will try to find a windows laptop in order to flash this image as it is listed in the supported images in the ut device page.

Do you know if there's a way to flash this image from a linux environment?

thank you

@Keneda
I had flashed oxygen OS 1.5.2 european version as it was a prerequisite in the ubports installer

@rubencarneiro
I installed the stable version and I upgraded to RC in order to check if this issue is resolved. Problem exists in both stable and RC version.

I can try downgrading back to the stable version if this will help us with debugging

@rubencarneiro please check below the pulseaudio logs after two calls (one outgoing and one incoming )

Hi @Timespansoul
I have restarted the phone several times and I have also tried to switch to speaker during calls.

Hi @rubencarneiro ,

thanks for porting Ubuntu touch for oneplus nord n100.
I recently installed UT focal rc using ubports installer.
Everything is working fine except audio in calls. I cant hear and they cant hear me. However, I have audio in other apps.

Please let me know of there's any workaround for this.

Thank you
