Moode Audio Player for Raspberry Pi

[terminalgrin]

Hi Tim,

I have tested 2.4 test release version 4, and I cannot make it work on my pi2 with hifiberry dac+ pro. everything looks and behaves like normal, but no sound is coming out. I ran the test image from hifiberry, so I know my hardware is working. are there any volume settings I might have overlooked?

 

thanks,

j

Hi,

 

In Moode System config:

 

(1) I2S audio device set to "HiFiBerry DAC+ Pro"

(2) reboot

(3) ALSA volume (%) should have a value in the field. If its blank/disabled with a message underneath "Hardware volume controller not detected" then it could be bug in Moode.

 

Please let me know :-)

 

Regards,

Tim

 

thanks for the fast response.

 

setting the alsa volume to 100 fixed it!

 

I did not understand the alsa volume setting, and since it said that the value was read at startup, i didn't dare to change it.

 

is it possible to not show genres in library?

is it possible to sort big and small caps together, not as it is now with big caps first then small caps? this works for albums, but not for artists.

 

thank you, donation coming.

Hi,

 

Glad its working :-)

 

Volume setup can be confusing for DAC's that have onboard hardware volume controllers because there will be two volume controls present, MPD and ALSA.

 

For the HifiBerry DAC+ and DAC+ Pro here is the recommended volume config:

 

In this config, MPD will be set to use "Hardware" volume control which means that MPD will control the DAC's onboard hardware volume controller via an internal coupling between MPD and ALSA.

 

(1) Set MPD volume control to "Hardware" (MPD config page)

(2) Set Logarithmic curve to "Yes" (Customize popup)

(3) Set Maximum volume (%) to 81 (Customize popup) this is 0db point for this DAC

(3) Move Moode volume knob to 10 then to 0 to establish initial MPD-ALSA volume level of 0

(4) Verify ALSA volume (%) is 0 on System config page

(5) Play a radio station or song file, adjust Moode volume knob to verify things are working

 

If the volume increases too much in the 0-50 knob range, set Logarithmic curve to "No" in Customize popup.

 

Regards,

Tim

 

after doing this, the overall volume level is very low.

Hi,

 

Thats odd. Should be same as the DAC+. I don't have one of these devices so its possible that its 0dB point is > 81% ALSA volume.

 

This can be verified by doing the following. Make sure nothing is playing !!

 

(1) ssh root@moode (pwd = moode)

(2) alsamixer

(3) right-cursor over to the main volume control. It should be named "Digital".

(4) up-arrow and raise the level until 0dB is displayed in the upper left of the alsa mixer screen

 

Let me know what the level is that yields 0dB

 

Regards,

Tim

 

On 0dB it reads 40. the same as the alsa volume in system config, if it matters.

Hi,

 

Correction. Above in bold should be "81% Maximum volume" referring to the setting under "Hardware volume control" in the Customize popup, not the ALSA slider level.

 

Attached is an alsamixer + Moode screen shot that represents the volume config in my earlier post for a HifiBerry DAC+. You can see that 0dB gain is reached at only 40 on the ALSA slider scale which translates to 81% max volume when Logarithmic curve setting = Yes. With this config, Knob 100 = 0dB.

 

The other alsamixer screen shot is for an IQaudIO Pi-DAC+ to use for comparison. Note that 0dB gain is reached at ALSA slider scale 100. The Moode settings are same as for the HifiBerry DAC+ except that Maximum volume % can be left at 100.

 

I'll ask Daniel (HifiBerry guy) over at the HifiBerry forum about the ALSA 0dB point for DAC+ and DAC+ Pro.

 

Regards,

Tim

 

the values are as you describe. I will check more music and settings tomorrow. looking forward to the clarification from Daniel.

 

thanks for all your help,

Hi,

 

In the meantime, to compensate for "low overall volume", set Max volume % to 100 in Moode Customize. This will allow ALSA volume up to 100 which will show +24 dB gain !!

 

Regards,

Tim

 

All is good now. maybe it was me being tired, maybe it was something technical. whatever it was, it works as expected now.

 

thanks again,

Are you using the afore mentioned config (MPD Hdwr vol, Log curve Yes, Max vol 81%)?

 

 

yes

[terminalgrin]

 

Question I have is whether there are any audio glitches (pop, tick, etc) when switching between clocks. For example when 16/44.1 track ends and a 24/96 track begins.

 

hmm, I feel like I'm getting a little bit of bit-envy. all my files are 16 bit (44.1). I downloaded a 24/96 file, but it does not appear anywhere in moode.

 

How does moode handle the fact that I have songs in a mp3 source that also exists in a flac source? they do not show twice in the library...

Tim, no weird sounds when going from 16 to 24 bit flac files.

Hi,

finally I had some time testing, and I found a couple of things.

 

When I went from playback via Airplay to normal playback the sound was distorted, and it turned out that the ALSA volume was now at 100, not at the normal 40.

 

When I add my complete library to the playlist, moode (or the browser I use) becomes very slow and sometimes completely unresponsive.

 

Is this known problems?
