Spotify no sound with 2.001 on rpi3 about volumio-plugins

[PaulFinch]

I think I have the same behavior with my Phat Dac, and I think it could come from a specific setting in
/etc/spopd.conf : output_name = ${outdev} resulting in hw:0 or hw:1 depending on the default one I guess ... Sometime, it could be the unused one.

In my case, I don't want to use this setting because I'm using a the softvol thing to control the volume (PhatDac doesn't have hardware volume control) so I get the sound but not "mixed"

Actually, volumio is quite sensitive when changing playback settings.
However, i managed to get it work by changing /etc/spopd.conf. Like I said i use the softvolume device. But I had to change output_name = hw:softvolume by output_name = softvolume

I seem to have the same issue
Hardware: pi0 + PCM5102 I2C DAC ('Hifiberry') with no hardware volume control.
I can play files off my NAS no issues, the software volume works fine. However, from Spotify, I have the same issues - No sound.
I did try what @PaulFinch suggested, and edited/etc/spopf.conf there, I initially tired output_name = softvolume but that didn't work. However setting output_name = softvol in /data/plugins/music_service/spop/spop.conf.tmpl fixed my issue :-)
Furthermore, I had a look as to where the ${outdev} is generated and have hacked in a little if statement to check if it's software or hardware device.

I have similar issue tested on rpi2 and rpi3 with Pi-DAC+, playback settings set to hardware. Spotify plugin has no sound and I've had to force output to hardware by changing output = hw:softvolume to output = hw:0 unsure why spotify plugin isn't picking up that the mixer type is set to hardware in gui.

Have just done volumio factory reset to try to replicate and it worked perfectly. 1) set up pi-DAC+ playback settings, 2) ssh into volumio and set both analog settings in alsamixer for IQaudioIO to 100% (as recommended in IQaudIO docs), 3) installed spotify plugin. output is set to HW:1 (card 0 is still onboard bcm chip) and all is working perfectly...

possible that the plugin gets confused when changing playback settings whilst installed which is what I may have had issues with when first time.
