Usb cable delay on playback

[WESTLOWER]

I have a play back delay problem using a USB Cable on Rpi3..
I have cheaper USB that plays with 4 seconds between tracks.
When i try the 'Posh' expensive USB cable (here on demo),
it turns into 30 + seconds between tracks! (sounds better though!):scratch:

I am using Rpi3 to USB/SPDif converter to a DAC. Picoreplayer and LSM.
Squeezebox app on iPad/iphone to control..
Any thoughts??

[pgarrish]

its broken?

maybe it has some circuitry in the cable, a buffer of some kind... But that is a long delay

[struth]

Even 4 secs seems excessive tbh unless its been set that way. Sounds like a compatability issue perhaps

[WESTLOWER]

cheers chaps
yes the 4 second thing maybe a setting in picore or LMS but the cables are the same length and the POSH cable still works so
shouldn't be an issue with a break or such.
Not sure how a USB cable (not powered) can be incompatible ?

Strange. The only thing that I can think of is that the fancy cable is so hopelessly out of spec, or damaged, that the system is struggling.

I've built a pi3 picoreplayer LMS server/player (Digi+ Pro) it does gapless perfectly well, and I'm not aware of any parameter in piCorePlayer that adds gaps between the tracks...:scratch:

The pi3 has more than enough grunt to easily run LMS and a player

Where do you store your music, on an HD connected locally to the pi? on a NAS? What size/speed SD card are you using?

[WESTLOWER]

Synology Basic Nas Drive, LMS stored on the NAS and flac files

Hard wired or wifi?

Have you always had a 4 second gap between tracks? That would drive me mad!!! :doh:

Do you have other squeezebox players in the system?

Did you expand the SD card on your pi?

[WESTLOWER]

WIFI Rpi
yes always a 4 sec delay
no other squeezes
not sure what you mean regarding the expand the SD card....

...more accurately 'Expand The FS' file system

It's on the main page, under advance settings...it won't do any harm

Presumably your NAS is wired? and has enough CPU/RAM to run LMS

and finally that you're playing files stored on the NAS

EDIT; Not finally...are you using the pi3's on board wifi, I'd advise not, I found it very flakey, get a 'plugable' USB one, and turn the pi one off in the wifi settings

[WESTLOWER]

Yes the NAS is hard wired, the RPi I am using the Wifi so
will Get a separate Wifi dongle and try that.. cheers

I use this with both the pi2 & 3...

...of course after all this analysis of the pi setup, the issue could well be downstream, but worth the upgrade anyway...;)

P.S. Did you manage to check out the CPU/RAM spec of the NAS?

Going a bit further with this, have you tried a wired connection - the playback gap shouldn't happen.
Wired gets the WiFi completely out of the way.

Fair point Chris...

It's bizarre that he doesn't get drop outs, only 4 (or 20) second gaps between tracks...:scratch:

That strikes me as being odd too.

I wonder if the posh cable is wired differently. Some cables don't have the 5V power line fitted, but if that were the case I'd expect it to either work like your original one, or not at all.

[WESTLOWER]

no drop outs or try few...depending who's online in the house...kids rinse it!
trued the usb cable at a mates house today and no deal at all, JRiver mini Mac and `DAC
so It looks like it could be the RPi or picture player or LMS...
complicated! but strangely I put the 'off the shelf' (normal) USB cable back in this evening and no delay at all...

Or more likely your WiFi ....

another vote for wifi as the culprit...

Wifi dongle on order

Just out of interest, which wireless router do you have?

[WESTLOWER]

Just a sky router...dunno what it is as I say badged up for sky
