PWD Bridge - problem playing 24/192 Flac files


#1

It does not happen with all 24/192 flac files.



But for some it keeps on throwing clicks and pops. Also most importantly sometimes a part of the song is skipped/jumped. I can see in the controller that the track is getting played smoothly. It is just that for some part the PWD is silent and then suddenly catches up.



Any idea ?



BTW I’m using a wifi setup between NAS and PWD rack through 2 routers. The main router is of AC type (the highest bandwidth so far available in the market). The other router (bridge router) is of N type. These 2 routers are connected through wifi. The NAS is connected with the main router. The PWD is connected to the bridge router router through ethernet cable.



I am using QNAP NAS with Asset UPnP server, Bubble PnP controller on Android Tablet. Typically the song are played smoothly without any single problem except in some of the cases.

Hiccups or skips are very often signs of a network problem. I don’t know anything about AC type routers, but the general wisdom is that for consistent, smooth playback of hi-res files you are best off with a wired connection. (I know that’s not always easy to implement, given walls and such, but it is the case.) Setting a static IP address for all your components may also help. Maybe someone else here has experience with AC routers and can confirm whether it’s possible to get consistent hi-res playback with them via wi-fi.

AC to n will result in an “N” connection and performance. Wifi seems to work best [for PWD/Bridge] if it can be line of sight or in an adjacent room with gyproc walls.

Older homes and 3rd floor to main floor are often problematic.

your choices are

1/ keep the same set up and investigate why only “some” files have the symptoms.

2/ hardwire your ac router to your moden with a longer cable so it is in the same area as your PWD and N router.

3/ buy a PLC ethernet extender [Netgear and Linksys have nice ones] attach one sender to your ac and the other to the N or even directly to the Bridge.

I know of no complaints about SQ doing this and it works like a charm.

There are other ways to skin the cat but the above would be a first suggestion.

Hi Gordon,



The last suggestion is implementable in my context. In fact I do have a pair of them which I took out when I read about SQ problem with the use of electrical line for sending data. But I can try put again.



Interestingly my other streamer Pioneer Elite N30 can stream the same set of files without any problem in same setup. So wondering is it spmething to do with configuration of bridge.



Like in my understanding streaming is all about memory play. So increasing the memory allocated to the process can help .

o- in 70% cases it's a busy disk issue
o- do not use USB disks
o- use a local disk connected to the server
o- in 15% it's a wifi issue
o- used wired when possible
o- in 13% it's a busy system
o- check the system load what you have skips, can it be an antivirus application?
o- the rest 2% is not significant, fix your disk first ;)

Is anything else running on your QNAP what may sporadically use disks? E.g. a torrent client? Try Minim server instead.

Check the process table on your NAS when playing. Minim server uses ~2% CPU even with transcoding.

Soooooooooooooooooooooooo… Looks like having a fast computer or NAS, and fast disks does help. Recently I moved from a 6 yo Intel Atom based NAS (QNAP TS-439) with WD Green disks to the latest TVS-671 with WD Reds upgraded to Intel i7-4790S, 16GB RAM. And… no more skipping.

What took 15%CPU on Intel Atom, takes 0.5%CPU on i7-4790S. WD Reds respond without delays, unlike WD Greens with old non-NAS firmware, that may suddenly freeze. And there is a plenty of free RAM (think disk caching, and no swapping). The underlying network is exactly the same.
