[Moto Z Play Questions & Answers] aviwdoowks:
This Poweramp player plays through OTG on our phone just fine. I do not think any other players do.

The current as well as beta 4 versions only gives our DAC 44k.

We can get our phone to play FLAC and DSD up to 24/192 without any USB DAC, or so it seems to me. See link to their beta support forum below.

I have submitted a request. Others could do the same. Be sure to attach the policy with your request. I mean the attachment, not the text, which I pasted so you all can analyze it.

From /etc.

Sign up and use the latest beta 4 (worked of me) for 2 weeks.

Our audio_policy.conf:

# Global configuration section:

# - lists input and output devices always present on the device

# as well as the output device selected by default.

# Devices are designated by a string that corresponds to the enum in audio.h

# - defines whether the speaker output path uses DRC

# "TRUE" means DRC is enabled, "FALSE" or omission means DRC isn't used.

# audio hardware module section: contains descriptors for all audio hw modules present on the

# device. Each hw module node is named after the corresponding hw module library base name.

# For instance, "primary" corresponds to audio.primary.<device>.so.

# The "primary" module is mandatory and must include at least one output with

# AUDIO_OUTPUT_FLAG_PRIMARY flag.

# Each module descriptor contains one or more output profile descriptors and zero or more

# input profile descriptors. Each profile lists all the parameters supported by a given output

# or input stream category.

# The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding

# to enums in audio.h and audio_policy.h. They are concatenated by use of "|" without space or "\n".
