Wanting to play a certain track from MicroSD on Chord Poly, but the glider App is playing a different track from another artist

They can finish syncing and verifying metadata. Each time they finish syncing, the song count changes. I load about 15 albums this time with DSD, Flac and Wav formats. The problem is now they are playing different songs from different albums again. Not all but most of them… this is so frustrating.

If you’re seeing the Verifying Metadata label on each sync, that means that the metadata verification is failing.

Since you’re running a test build of Glider, I’m able to see some remote logs from your device that are telling me that the network requests are failing while attempting to download the metadata for those DSF files. This either means you’re having network trouble or the Poly is unable to serve the files Glider is requesting due to some other reason.

is there anything i can do to verify and fix this problem Joe?

You may need to contact Chord support about your network troubles.

I found the issue. it’s related to unstable home wifi network most likely. I turn poly into hotspot mode it seemed ok for a few days. Last night I added 2-3 albums and glider is playing another track from a different album again. I will try to delete the metafile and see if everything is ok.

A post was split to a new topic: Add a ‘Rebuild Index’ feature

At first, I thought it’s my home WIFI having this issue, I change my settings and turn my poly into Hotspot, and use my mobile phone 4g network for internet. It worked as I was able to sync, verifying the Metadata. After testing for a few days and as I purchased more albums from HDtracks and put them into my microSD and load Glider, the same problem happened again. it cannot finish the metadata.

I understand if my home WIFI maybe unstable but the hotpot of poly and the 4G internet on my phone is very stable. I am not sure why am I still having this problem of playing the songs properly.

Most of the new albums loaded it were ok, then when I play the old existing albums, they start playing some other songs. I don’t know what to do already…

joe 2018-09-10 17:44:56 UTC #31

Can you please try the following:

Set your Poly in Hotspot mode and connect your phone to Poly’s hotspot
Delete Glider and re-install from TestFlight
Now attempt to reproduce the problem without switching network modes

Hello, I am having a similar issue. In my case, the SD card has 2K untagged wav files organised in folders by artist > album. Each album folder contains the album cover jpg. In my case, I can browse through the folders and play the songs. The artists remain “unknown” as expected due to missing tags in the wav files. The album cover in the folder is overlooked, and in its place glider shows pictures of albums that have nothing to do with the actual music file. I am afraid that untagged wav files are a case which is managed badly by the system. Can this be the case?

joe 2018-09-23 19:15:27 UTC #33

What’s likely happening here is that Glider is picking up at least one cover art for the group of all songs that have been placed in the ‘Unknown Album’, and is showing that album cover for all of your unknown songs. I’ll look into fixing this.

But you can fix this on your end by simply adding the appropriate metadata to your WAV files. It’s a common misconception that WAV files can’t contain metadata, but this is not true. Most tag editors work just fine with WAV files, including Kid3: https://kid3.sourceforge.io/.

simoneratti 2018-09-23 20:08:26 UTC #34

I have always preferred to avoid tagging wav files as some programs can fail managing them. As for the covers, why doesn’t glider look for pictures in the working folder?

joe 2018-09-23 20:13:55 UTC #35

Glider doesn’t typically have access to the file system, and relies on the metadata being sent over whichever protocol is in use. Can you tell me a little more about your setup?

I would recommend adding the metadata to your WAV files as I’ve yet to come across a situation where this would be problematic.

simoneratti 2018-09-23 20:43:28 UTC #36

I have started using glider today, having bought a chord mojo + poly. I would like to use glider to play the sd card content. I have noticed a long time to index the sd card, which is another cons of the combination. A long indexing impacts card switching. The reason why I have wav without tags is that I normally use roon which fills the metadata gap.

joe 2018-09-24 00:46:23 UTC #37

Yes, this is very much a tradeoff. The upfront cost of syncing your metadata enables most of Glider’s unique feature set including the ability to instantly search, sort and shuffle your entire library across multiple sources.

If you don’t care about these features then you can simply browse by folder, which is done in real time and does not require a sync to be completed before hand.

simoneratti 2018-09-24 05:53:35 UTC #38

In fact, browsing through folders is what I currently do to get the benefit of switching card quickly. A smart use of pictures in folder, and file and folder names would workaround missing tags, making feasible the use case of card switching without the penalty of unknown data displayed during playback.

joe 2018-09-24 14:16:00 UTC #39

Yes, but this feature would need to be requested of Chord to convert your filename and artwork information into the metadata sent to connected DLNA clients. Glider has no access to the filesystem, so it doesn’t actually know what your file names are or that a cover.jpg file exists.

As an example, I’ve loaded up an untagged WAV file on the SD card of my Poly, and here is the entirety of information available to Glider about the file while browsing by folder:

<item id="64$0$0$0" parentID="64$0$0" restricted="1">
  <dc:title>The Gaslight Anthem - The '59 Sound Sessions - 01 The '59 Sound</dc:title>
  <upnp:class>object.item.audioItem.musicTrack</upnp:class>
  <res size="33151484" duration="0:03:07.933" bitrate="1411200" sampleFrequency="44100"
       nrAudioChannels="2" protocolInfo="http-get:*:audio/x-wav:*">
http://10.0.1.22:8200/MediaItems/24.wav
  </res>
</item>

You can see there is no artist, album or artwork information. The file name has been used for the title, which does display properly in Glider along with the parent folder name:

Now I get you! What tagging software do you recommend on macOS? Is there a software that can automate the process?

joe 2018-09-25 01:41:11 UTC #41

I personally use Audirvana or Kid3 on my Mac. If you’re looking for something automated, you can try MusicBrainz Picard (free): https://picard.musicbrainz.org/, and SongKong (not free): http://www.jthink.net/songkong/

I sometimes have the same problem. Redownloading the app helps…

Beiriannydd 2019-02-09 00:10:25 UTC #43

I have experienced this but I also found a solution! It was working fine for me on my home network but refused to play DSD while in Hotspot mode. I eventually looked up ‘chord.audio’ and got the IP address 192.168.1.1. I added this manually to Glider as an MPD server. All of a sudden I can play my DSD through the entry labeled [MPD] but not the one labeled [uPnP]. The problem could maybe be one of DNS resolution when the WiFi can resolve the name but the Phone connection cannot.
