Dropped

All working as it should in AOSP9 based port: [logcat_hybris9_works.txt](https://github.com/sailfishos-sony-tama/main/files/6095023/logcat_hybris9_works.txt) Echo in AOSP10 based port: [logcat_hybris10_echo.txt](https://github.com/sailfishos-sony-tama/main/files/6095041/logcat_hybris10_echo.txt)

I wonder, whether /sparse/etc/pulse/xpolicy.conf.d/voicecall.conf is needed. Right now, carried over from Seine

Dropped /sparse/etc/pulse/xpolicy.conf.d/voicecall.conf and not much changed. Probably not needed for Tama. Interestingly, there is major echo in AOSP10 as well. In my build and seems to be there in PixelExperience...

Stock Android 10 does not have such echo as AOSP10 variants

Experimenting on SFOS hybris-10: Reverting https://github.com/sonyxperiadev/device-sony-apollo/commit/ee4982625e2720669eb3e513f9cb4f02618b8df9 seems to reduce it somewhat. But it is still there Switching to older ACDB didn't help, unfortunately.

As from more testing, reverting increase in microphone sensitivity dropped echo to very small, I will revert the commits increasing microphone volumes and we can adjust the levels later as...

Current fix includes building with the reverted commit, as described in https://github.com/sailfishos-sony-tama/main/blob/hybris-10/hadk-sony-xz2.md

We will have to test it within the port and see what works best. Looks like AOSP devs are too busy with AOSP11 and maybe it is not an issue...

@pagism: Please check whether phone calls work fine for you on XZ3. In terms of echo and microphone sensitivity.
