Official moOde 8 support thread

[TheOldPresbyope]

I'm still hunting down my i2s sync error issues and in so I keep coming across this, assumed to be unrelated, error when I am looking through the /syslog

Code:

Apr  3 15:43:24 moode winbindd[647]: [2022/04/03 15:43:24.362424,  0] ../../source3/rpc_server/rpc_ncacn_np.c:454(rpcint_dispatch)
Apr  3 15:43:24 moode winbindd[647]:   rpcint_dispatch: DCE/RPC fault in call lsarpc:32 - DCERPC_NCA_S_OP_RNG_ERROR
Apr  3 15:43:24 moode winbindd[647]: [2022/04/03 15:43:24.364199,  0] ../../source3/rpc_server/rpc_ncacn_np.c:454(rpcint_dispatch)
Apr  3 15:43:24 moode winbindd[647]:   rpcint_dispatch: DCE/RPC fault in call lsarpc:32 - DCERPC_NCA_S_OP_RNG_ERROR

...

I can't speak to your 24/96 issue but this output to the syslog is known to the moOde devs. It started showing up with the bump to Raspberry Pi OS 11 (bullseye) and, yes, It's not related.  Sooner or later we'll figure out why it's occurring. I showed it could be eliminated simply by not including winbind (wins) in the network services but we're not certain we want to do that.

Hello community, hello Tim,
2 days ago i update to the new V8.
My Hardware: raspberry pi4B with ALLO Boss DAC2

I always select Mixter Type: Hardware cause it sound better than software.

When i rotate the volume controller the sound stops sometimes, hanging.

In Moode 7 it always works fine.

Is that a bug that might be fixed?

Thank you.

[Tim Curtis]

I have a Boss 2 but don't recall experiencing the issue you described. I can run some tests today.

When you mention "the sound stops sometimes, hanging." what does "hanging" mean? Do you have to reboot or power cycle the system?

it occurs again, open an SSH terminal and post the output from the commands below.

Code:

mpc status

amixer -c0

Bug description:

No sound at all whenever I start streaming FLACs from my NAS.
Then, when I play with the volume knob:

• Sound comes out from left speaker only
  
• sometimes from both speakers, but with something like a 90/10% level balance
  
• or bad rendition (either way too much bass, bass distortion or "cold" sound)
  

Absolutely no issue when streaming from Spotify.

My setup:
HifiBerry DAC2 HD hat on Raspberry Pi 4 Model B

In Audio Config 
- Set DT overlay to None
- Reboot 
- Set DT overlay to hifibery-dacplushd
- Reboot

Post the output from the commands below.

Code:

cat /boot/config.txt

amixer -c0

Please note that I can't reproduce the issue anymore. Launched my raspberry this morning and sound was OK on both speakers/channels. Might be a false positive or I got something wrong at the first time.
Anyway, here's the output you asked for. Thank you Tim!

I tested on an Apple Air pad also, here the feedback is a little bit faster. The music isn't playing gapless when i rotate the volume controll faster.  I think Frank79 and I have the same problem. Some steps on the volume rotation
switch to 0% volume, told me the mpc status, see attached picture..

I ran a few tests on my Boss 2 and no issues with volume.

One thing in your amixer output thats very strange is that the volume shows [100%] but [-50dB]. This makes no sense since at 100% volume it should be 0dB. This might be a symptom of whatever is causing the volume issue.

Code:

Simple mixer control 'Master',0
 Capabilities: pvolume pswitch
 Playback channels: Front Left - Front Right
 Limits: Playback 0 - 255
 Mono:
 Front Left: Playback 254 [100%] [-0.50dB] [on]
 Front Right: Playback 254 [100%] [-0.50dB] [on]

ETA: Disregard comment about -50db. As @jonners pointed its actually -0.50 dB which is close enough to 0dB.

[Mr.R0b0t]

disable bluetooth = again http site dead ;-)

[jonners]

@Tim Curtis


i see -0.50dB, not -50dB.

lol, yes indeed it is. I'll go back and edit that post!
