AOSP13 Xperia10V and Xperia10III bad voice on voip/jingle audio/video calls

[PaoloP79]

Platform: zambezi, lena
Device: pdx235, pdx213
Kernel version: 5.4.210-qgki-g861b0a36658e, 4.19.248-g92372ee24825
Android version: android-13.0.0_r75
Software binaries version: SW_binaries_for_Xperia_Android_13_5.4_v2b_zambezi, SW_binaries_for_Xperia_Android_13_5.4_v4b_zambezi, SW_binaries_for_Xperia_Android_13_4.19_v4a_lena

NOTE: For device pdx235 I need as software binaries SW_binaries_for_Xperia_Android_13_5.4_v2b_zambezi because otherwise the camera is not working, as I reported in a previous issue.

Previously working on
xperia10III with android11 worked fine

Description
I've two communicating phone, let me say a xperia10V or xperia10III and my phone (not an xperia). Both phones are using the same messaging app.

Symptoms
When I make a call (either audio or video), on xperia side the received voice is bad (it seems like Donald Duck speaking), while on my phone side I can hear my voice perfectly.

How to reproduce
Install an app, can be whatsapp, conversation or monocles (the three I tested) and make a call.

Additional context
Once the phone call was set up I can read from logcat lots of errors like

11-05 17:51:48.117   777  7465 W audio_hw_primary: out_write: underrun(6656) frames_by_time(243) > out->last_fifo_frames_remaining(0)
11-05 17:51:48.118   777  7465 W audio_hw_primary: out_get_presentation_position: avail:296640 > kernel_buffer_size:1920 clamping!

Inside the file log.txt there is a full logcat of an xperia10V when I receive a call with whatsapp, it shows exactly the same behaviour with conversations.

Thankyou in advance for your attention.
Best
Paolo

On it. Thanks for the report!

I found the reason. It's completely my fault. When I updated the HIDL Audio HAL to version 7.1, the audio policy was also updated. I wrote a script that dumped the stock audio policy and updated its XML schema.
However, since the stock configuration comes with at least three different configs:

• /vendor/etc/audio_policy_configuration.xml
• /vendor/etc/audio/audio_policy_configuration.xml
• /vendor/etc/audio/sku_{platform}/audio_policy_configuration.xml

The last path was selected as the primary one because it is used by most platforms. Unfortunately, some mid-range platforms like Murray, Zambezi, and Lena use the second path.

I will manually check each platform and send a fix.

Once again, I deeply apologize.
