@Mukul Kalsait same happens to me, redmi note 9s miui 13 Android 12, has to go back all My audio settings to default, if I use hi res the volume turns lower even using My USB dac, it was working perfect with 942.

@Mukul Kalsait  @Luis David García Solano With the newer versions having more access to the actual hardware capabilities of your devices, you will need to reset the audio output options first. Old settings may not work once the hardware information has been accurately updated based on the device.

@MotleyGallready done but dosent work for me . Thankyou for your suggestion.

@Mukul Kalsait @Luis David García Solano  Thanks for the reports. There have been some changes made to the hi-res detection process, largely to help with issues in Android 13, but as with any beta-test release there may be unexpected repercussions too - that's the point of test releases, to find these sort of issues before unleashing changes on the whole market.

@Luis David García Solano Could you provide more details, such as the external USB DAC you are using and the Audio Outputs Detection Log (found in PA Settings=>Audio=>Advanced Tweaks).

 

The last stable release was build 939, which can be downloaded from: 

If you want to roll back, you will need to do a full uninstall first, so please make sure you export/backup your Settings/Data first so you don't lose any internal playlists, ratings, etc. As you are going to have to perform a clean install anyway, could you perhaps first try clearing app data for 944, so it thinks it is a new installation, and see if the problems still persist before you roll back?

@Mukul Kalsait use Restore Defaults on your hi-res output. This should (probably, depending on ROM/device) enable No DVC option that will enable "real" hi-res, not just incorrect info as shown previously. The "issue" is mostly for Snapdragon based devices on Android 10-11 which are not capable to output hi-res + DVC on 3.5 and sometimes on USB or BT. Issue is in quotes as this is non-issue. For hi-res you don't want DVC.
