HiFiBerry Volume Control - audiocore - 01-03-2020

Hi there,

I am using a HiFiBerry DAC+DSP with dsptoolkit in moode audio. dsptoolkit is a python the interface that allows to control DSP functions.
In alsamixer I have "DSPVolume" as volume control. Strangely it is not affected when changing the volume in moode audio.
Does moode audio control directly the HiFiBerry DAC+DSP by software and is independent from alsamixer? Do they somehow interfere?

Thank you very much in advance Smile

These are my moode audio settings:

Code:
A U D I O   P A R A M E T E R S

Audio device = HiFiBerry DAC+ DSP

Interface = I2S

Mixer name = Digital

Hardware volume = None

Max ALSA volume = 100

Audio source = Local

Output device = Local

Resume MPD = No

Volume knob = 63

Volume mute = Unmuted

Saved MPD vol = 0

Preamp volume = 0

ALSA version = 1.1.8-1+rpt1

SoX version = 0.1.2-3

This is the output from aplay and amixer:

Code:
pi@moode:~ $ aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0]

  Subdevices: 0/1

  Subdevice #0: subdevice #0

pi@moode:~ $ amixer

Simple mixer control 'DSPVolume',0

  Capabilities: volume

  Playback channels: Front Left - Front Right

  Capture channels: Front Left - Front Right

  Limits: 0 - 255

  Front Left: 207 [81%]

  Front Right: 207 [81%]

An exception to assign the correct mixer name would need to be coded into function getMixerName($i2sdevice) in source file playerlib.php. https://github.com/moode-player/moode/blob/develop/www/inc/playerlib.php

Hello Tim,

thank you very much for your answer and the solution. I just changed the code and it worked! Smile

Now "hardware" volume control appears under audio settings. I guess its DSPVolume then.

Thx again! Time to enjoy some moode Smile
