[PROBLEM] Tics when playing high-resolution PCM files

[DRONE7]

I used to connect USB HD to router ad use it as a network source,
but latest versions of moode does not support share SMBv1 anymore,
so I should buy a NAS, but for less money I prefer to buy a Raspberry 4
when it will be available again

Ouch!...you're using a router so old that it does not support current Samba versions ?  
What router and surely there is either an update firmware or cheaper...and more secure !.. to buy a new router than a Pi4 ?

is the router provided by the internet connection provider,

in theory I couldn't use another one.
It's a quite modern and good one, however,
Zyxel VMG8825-B, but no firmware updates that enable sambav2

AFAIK Linux still supports Samba v1. You might have to add vers=1.0 to the advanced mount flags in Music Source Config.

Samba v1 was removed from kernel 5.15

Ok thanks for the info :-)

Hello,
when I play hires PCM files
I hear occasional but very annoying "tics".
It happens with some 24/96, 192 and 352 Khz flacs.
On 352 flacs they are more frequent.

I suspect the issue is due USB lags
on external HD, or on USB dac.
I have Moode 8.1.2 64 bit on RB 3B+, connected to a topping DX5 usb dac
and external USB 1 TB 3.5 disk.

no errors in moode.log

The two 352.8K FLAC files that you provided played perfectly for me. There were no audio glitches whatsoever. 

The system I used was an Allo USBridge SIG (Pi-CM3+) and USB attached Allo Revolution DAC. The files were on a USB stick.

As I reported to you privately, I had essentially the same results as Tim reports when I played your tracks in various circumstances.

OTOH, I clearly heard the glitches in the recording of them you subsequently provided. You reported in your message #3 that the glitches disappeared when you played your tracks from local (SDCARD) storage so I assume this latter recording was made while playing the tracks from local attached USB HD drive.

It's been my experience that problems such as this one rarely occur because "on Raspberry USB ports are not indipendant but share bandwidth". However, you can easily test this hypothesis by following @DRONE7's suggestion and try playing the same tracks from a local USB memory stick.

If you have a powered USB hub at your disposal, you could also try connecting the USB HD drive through it to your moOde player. Such hubs provide extra signal isolation.
