How can I unmute my Dragonfly dac in Runeaudio?

It works fine with Volumio.

Setup:

Raspberry pi B+ v1.2
8 gB Sandisks ultra w/ runeaudio (latest alpha and beta)
Audioquest Dragonfly
several USB drives

Thanks!!!

ssh into the Pi and use alsamixer, select F6 to choose the DragonFly and then hit the M key to unmute.

Hi doxyq3,
you could quickly check if your card is set to mute in this way:

  1. access to your Rpi via SSH (user: root, pass: rune),
  2. type alsamixer in the command line,
  3. press F6 and select the Dragonfly DAC from the list,
  4. check if the mixer volume bar has an "infinite" symbol or a "M" at his base.
In the second case, your card is muted: press "M" to mute/unmute the card.

Thanks!!!!!!!

Volume was unmuted but set to minimum, up arrows raised volume to max and sound works now :D

But..... the hardware volume control doesn't work and sound pauses a second every 2 seconds on 24bit/192k files :(

Software volume works but I would rather us the DACs hardware volume like in Volumio and 16bit/44k & 24bit/96k files play fine.

When in software volume mode, volume will vary and all formats 16bit & 24bit - 44k-192k files play fine.

Hardware volume mode is the problem, with no volume control and 24bit 192k files stuttering.

Typing aplay -l shows:

card 0: ALSA [bcm2835 ALSA], device 0 bcm2835 ALSA [bcm2835 ALSA]
Subdevices: 8/8
Subdevice #0: subdevice #0

Subdevice #2: subdevice #2
Subdevice #3: subdevice #3
Subdevice #4: subdevice #4
Subdevice #5: subdevice #5
Subdevice #6: subdevice #6
Subdevice #7: subdevice #7
card 0: ALSA [bcm2835 ALSA], device 1 bcm2835 ALSA [bcm2835 IEC958/HDMI]
subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Dragonfly [Audioquest Dragonfly], device 0: Usb Audio [Usb Audio]
Subdevice #0: subdevice #0

I'm sorry but I'm totally ignorant with Linux. I don't understand a lot of the posts. Thank you for bearing with me.
