It always falls to 48kHz. It's weird.

@c4pp4 It is strange though, that there is no documented way of getting the ubports version of android to use rootfs-overlay, just as the snap version does. Indeed, repacking the squshfs isn't such a big deal (although I wouldn't have known of the parameters you used, but still, just dropping a file into the overlay directory tree would make things so much easier!
BTW, the sound that you get from android apps after completing this step is quite choppy, not really suitable for real use, more a proof of concept.

@fredldotme said in Sony Xperia X (suzu/F5121 & F5122):

@c4pp4 nice catch!

What you can do to test small modifications to the Halium portion (where this file is from):

• Reboot into recovery
• Connect to the device via ADB
• Mount the Halium system image: mount /system/var/lib/lxc/android/system.img /tmp

There is no directory /system/var/lib in recovery mode, I also cannot find a system.img anywhere. Has this changed recently?

• Edit the Halium override file to your liking: nano /tmp/halium/etc/pulse/touch.pa

Wouldn't this be the file /system/halium/etc/pulse/touch.pa?

EDIT: losetup -a says that /dev/loop0 is pointing to /halium-system/var/lib/lxc/android/system.img, yet there is no directory /halium-system. How can I access it?

@fredldotme thank you so much for your awesome work. I just flashed the port a few days ago and everything is working super smooth.

I followed during the installation process your instructions and of @christophe14 (post 160). It helped me a lot.

The ubports installer caused a lot of trouble during the installation. I got a lot of error messages (they are already on github). The biggest problem for me was for some reason to boot into fastboot mode. It took me easily 40 attempts. Don't know why. For some reason the ubports installer also did not recognised the device (all the necessary drivers were installed. Switched over to the installer on fedora and did not had any problems.

Keep up the great work. I am amzed by this wonderful community and what you all have already achieved.

@jro
What is the output of

adb shell ls

when the device is connected in recovery mode?

[c4pp4]

Some audio tweak:

• boot device into recovery

• mount system.img:

adb shell mount /system/var/lib/lxc/android/system.img /tmp

• when playing 44.1 kHz audio stream the sound is crackling, default sample rate is 48 kHz and I think the resampler is too slow, fix it using higher latency via deep buffer flag:

adb pull /tmp/etc/audio_policy.conf
sed -i '/AUDIO_OUTPUT_FLAG_PRIMARY/{s/FAST/DEEP_BUFFER/}' audio_policy.conf
adb push audio_policy.conf /tmp/etc

• ringtone volume is too low, it's played via output-speaker+wired_headphone port, set appropriate acdb_id:

adb pull /tmp/etc/audio_platform_info.xml
sed -i '/Custom mapping starts here/a \        <device name="SND_DEVICE_OUT_SPEAKER_AND_HEADPHONES" acdb_id="799"/>' audio_platform_info.xml
adb push audio_platform_info.xml /tmp/etc

• sound is distorted when max volume is used, correct max volume:

adb pull /tmp/etc/mixer_paths.xml
sed -i -e '/RX7 Digital Volume/{s/92/86/}' -e '/RX8 Digital Volume/{s/92/86/}' mixer_paths.xml
adb push mixer_paths.xml /tmp/etc

• umount system.img:

adb shell umount /tmp

• reboot the device

@c4pp4 Wonderful, aber you able to integrate this permanently into the system image with a PR on Github? Your solution is too complex to apply and also will be overwritten by an update

[fredldotme]

Yeah, those changes presented as a PR would be highly appreciated! I'm currently occupied with a lot of other things, so I probably can't do it myself in the short term. The files you're modifying are probably in the suzu and loire repos on GitHub linked in the top post.

[fredldotme]

Thanks again to @c4pp4 for preparing those changes as a pull request, the changes will land within the next two days.

[c4pp4]

@fredldotme
No problem

I'm trying to achieve 44.1 kHz as the default rate or find out why is resampler too slow. I'm not sure if it's pulseaudio server, droid module or qcom driver related or something else.

[c4pp4]

@fredldotme
I think I find out why it's always using 48 kHz. It's related to qcom/audio/hal. According to this commit https://github.com/fredldotme/device-sony-common/commit/b3235f337a371d7746fe591e3adcaca99c90dc4f we are using qcom/audio/default/hal/audio_hw.c where adev_open_output_stream function is always assigning 48 kHz rate regardless of what we configure in audio_policy.conf/touch.pa:

3065       out->sample_rate = out->config.rate

newer version contains:

5295       if (config->sample_rate == 0) {
5296                   out->sample_rate = out->config.rate;
5297               } else {
5298                   out->sample_rate = config->sample_rate;
5299       }

Is there a chance to test patched version?

@c4pp4 you could build your own Halium image and test it that way. The build instructions are here: https://github.com/Halium/projectmanagement/issues/98

Just build the systemimage, run simg2img, e2fsck and resize2fs on it and put it in /system/var/lib/lxc/android/system.img.

[c4pp4]

@fredldotme
Thank you!

@fredldotme
I've patched it and successfully built and tested.

@c4pp4 looks sane at first glance. It would be interesting to know how it behaves with different sample settings provided through the touch.pa file. Does it now allow forcing the sample rate that way? In that case even better, but it looks like it should work on all Sony devices.

Would you like to prepare a PR for it, so it has your name in the commit history?

[c4pp4]

@fredldotme
It should work on all devices using 'hardware/qcom/audio'. Now it takes default settings from pulseaudio (44.100 kHz) if it's not specified through /etc/pulse/daemon.conf. You can override it changing 'default-sample-rate' parameter. You can change the sampling rate through /etc/pulse/touch.pa as well using 'rate', 'sink_rate' or source_rate' parameter when loading module-droid-card-24.

[fredldotme]

@c4pp4 awesome stuff! Should give us more flexibility should the default not provide a sufficient audio experience. Will you prepare a PR for it? I'm currently off my normal setup, only carrying a backup of Halium 7.1 on a microSD card.
