Google’s got a new way to update your Pixel’s audio libraries

• A new app called Pixel Audio Services looks like it can update your Pixel’s audio libraries without a system update.
• The app is visible on the Play Store now, but the listing we’ve seen is only compatible with Pixel 10 phones.

Earlier today, 9to5Google spotted a new app on the Play Store called Pixel Audio Services. The Play Store listing says that the app is meant to provide “updates and bug fixes of audio modules,” which is a bit vague. After poking around the app, though, we now have a better understanding of what it’s meant to do.

Android’s system files include specific instructions that let the operating system know how it should interface with hardware audio components, like the DAC and amplifiers that power a given phone’s built-in speakers. These instructions live in XML files that can be found in the /vendor/etc/audio directory. Updating files in the /vendor partition has historically required a system update, but the new Pixel Audio Services app provides a workaround that could help Google fix audio bugs more quickly.
