Official moOde 7.5.0 support thread

[ElmhurstFun]

I tried Spotify on 7.5.0 last night.  It took several minutes of hair pulling over why I got no sound before I accidentally pressed the volume control on my phone.  I have Spotify set to 100% initial volume and completely forgot that the volume is actually controlled by the phone/control point.  Seems that the update resets the initial volume to 0.  I record this here just in case a fellow traveller is on the same road.

One thing I have noticed with Spotify Connect on 7.5.0 is that when i adjust the volume by pressing volume up/down buttons on my iphone, the result is stuttering/dropout on Moode as the volume 'catches up' over Spotify Connect.  I don't recall this happening previously... it was a little laggy in raising/lowering the volume but it didn't actually interrupt the music.    I may try a fresh install to see if there's any improvement

I actually noticed this too last night.  Most of my players have maximum volume all the time (downstream amplifiers control the volume), but one in an old radio in the kitchen uses in-player controls.  I rarely listen to Spotify on that one, but did just last night.  I wondered if it was simply that I'm using a Pi Zero and it can't cope.  What hardware is yours running on?

That is a common element between us!   This is on a Pi Zero W, with a Hifiberry DAC+ Pro HAT.   I know the librespot version changed in this release, so maybe that is a factor.  I will experiment this weekend with the clean install (I had in-place upgraded from 7.4.1) and I have plenty of larger PI's I can test with to see if the Pi Zero is the root or not.

I've just tried the different volume curves in the Spotify renderer and they all have the same behaviour.  I'll try adjusting the volume on one of my RPi4 based players tonight.

Seems like it's the Pi Zero.   I did a fresh install of 7.5.0 and that didn't help.   I then tried it in my RPi 400 and did not have the skipping/interrupt behavior -- I raised/lowered the volume from my iphone and also from a PC client and the spotify connected Moode Rpi 400 worked as expected.   I suppose I could revert back to 7.4.1 but its not a huge deal and I probably listen to more things MPD than Spotify Connect.   I could replace it with a larger PI but really love the form factor of the PiZero for my desk -- a user on Thingiverse did a great 3D print case design for PiZero with Hifiberry DAC+ Pro HAT.   Sounds great attached to some Beoplay S3's.

You may find a suitably-sized replacement with a quad-core 64-bit ARM Cortex-A53 processor in the recently released Raspberry Pi Zero 2 W

Yup, my testing agrees with yours.  No issues on my pi4 based players.  I find it only skips when the volume is pressed more than once in a row (or held down).  A strategy of single presses and pauses will raise or lower the volume without stuttering, but obviously takes a longer time to make big adjustments.

Try toggling the Screen blank option on System Config leaving the final setting at "Never"

After reboot and some "toggling" everything is back to normal !
Thanks a lot for the help, and again good job !

Hello again,
do we need to do an ?

Code:

apt-get update and upgrade

If yes, must it be done before or after the moode update ?
Is there any advice to not break whole installation ?
thanks

It is not recommended to do apt-get upgrade at any time.  The supported configuration is the one shipped, an upgrade would introduce variables in the setup that would prove difficult to support (did it break because of the upgrade, if so, which bit, etc.)

librespot 0.3 introduced dithering which can be taxing on lower-end hardware. You could try on your Pi Zero with dithering disabled.

Alas turning off dithering had no effect.  Nor did dropping the bitrate.
I may mention it on the librespot support forum, see if anyone else over there sees the issue.

I am one of the librespot maintainers. I can't say I've heard of anyone else reporting this. Which isn't to say it can't be an issue because at least you two are obviously encountering it. Hence my interest.

We target the RPi Zero as the lowest-powered device that we support. I don't have one, but one of our members does, and he tested both the dithering and 64-bit sample pipeline on it. So at this point I don't understand what's going on, but think it's worth pursuing.

When you run top, what CPU and RAM usage do you see? What's the current load? Perhaps high I/O usage or blocking? We'd have to investigate further and I can't reproduce.
