Possible mixer name parsing issue. Its not affecting playback in your configuration because you have MPD mixer type set to "Fixed (0dB output)". The parsing issue is fixed in upcoming 7.4.0.

Code:
20210831 162244 worker: ALSA PCM volume set to (amixer: Unable to find simple control 'PCM',0)

Please post the output of the command below so I can confirm the parenthesis parsing issue.

Code:
amixer -c 2

For DSD playback try the following settings:

Audio Config: ALSA output mode "Direct (hw)"
MPD Config: Either DoP or Native.

Thats odd. Typically the volume mixer(s) for a device will appear like below with a left and right channel and current dB values.

Code:
Simple mixer control 'Master',0

  Capabilities: pvolume pswitch

  Playback channels: Front Left - Front Right

  Limits: Playback 0 - 255

  Mono:

  Front Left: Playback 159 [62%] [-48.00dB] [on]

  Front Right: Playback 159 [62%] [-48.00dB] [on]

What is output from command below?

Code:
sudo /var/www/command/util.sh get-mixername

ETA: You can also try the command below to see if it correctly picks up the volume mixer. You will see a vertical bar and the mixer name below it.

Code:
alsamixer -c 2

DaleB · 08-31-2021, 11:27 PM

The SUDO command output nothing:

pi@moode:~ $ sudo /var/www/command/util.sh get-mixername
pi@moode:~ $

alsamixer -c 2

After ALSA output mode = "Direct (hw)" and MPD Config = Native, DSD256 plays OK.
The MPD Config was already Native, so the ALSA mode made it work.

FYI - With Direct(hw) mode DSD256 works, but Airplay stops working. Vice versa when mode is (plughw).

**Tim Curtis** · 09-01-2021, 01:32 AM

When using the Direct (hw) output mode which does not perform any automatic format conversions you would need to set Airplay bit depth to 32-bit in Airplay Config since this device reports that it only supports 32-bit over its USB interface.

You could also try setting MPD DSD support to DoP if this device supports it. If it doesn't support DoP or native DSD then you are not really getting DSD format rather you are getting DSD converted on-the-fly to PCM.

The alsamixer screen shot doesn't appear to show any hardware volume mixer for the device which is very odd.

**TheOldPresbyope** · 09-01-2021, 02:48 PM

From the moodeutl -F output in post #11 we see that the DAC does not report support for native DSD

Code:
Card 2, ID `DAC52990006', name `ADI-2 DAC (52990006)'

Device 0, ID `USB Audio', name `USB Audio', 1 subdevices (1 available)

2 channels, sampling rate 44100..768000 Hz

Sample formats: S32_LE
