Description of Issue
When I use Roon ARC and download my favorite playlist to my phone (140 tracks) - it takes quite a long time, although connection speed is not an issue. At the end I face corrupted tracks during playback. I did that in the initial version of the app, but also tried with the new build, hoping this issue was fixed, but still I face the same issue (it shows toast message, that the track is corrupted). And I have to delete the whole download (140 files) and start over again - there is no way to re-download single corrupted track.
I have rhe same issue with some corrupt files in a playlist. Even while playing without downloading. In the normal Roon app I can play these files without problems.
I have been running into the same issue on iOS except for me it is whole albums. deleting the download and re-downloading doesn’t seem to solve it either.
Im afraid its not gone for me. Using iOS. I have one album (so far) on my server that will play only some of its tracks via ARC with the others showing a bright red “Corrupt media” banner across the bottom of the iPhone screen. All tracks in this album play fine via regular Ron app on home system. This occurs on ARC whether the tracks are streamed from the server or downloaded and played from the phone,
What I did is deleting the existing local downloads and redownload them with the new version - since the files streamed well I thought there could have been an issue with the download files. Did you try that?
Yeah I just went through album by album of those I downloaded and had to delete well over half of them as they were all corrupted. In many cases it is entire artist catalogs and not a random album here and there which makes even less sense to me. I have tried multiple times to re-download the corrupted albums only to find they are still corrupted.
This has made the app unusable at this point for me, as offline access was to be the biggest benefit of it. I am pretty frustrated to be honest and am now replacing those that I can via Qobuz (though clearly their catalog will not always have replacements for some of my own library). I would love to hear what the Roon staff has to offer as this seems to be a growing problem rather than a one-off…
so I I installed the latest Roon and ARC updates then downloaded the Abbey Road Deluxe Edition to my I Phone. One track refused to complete - “The Long One” - so I removed the download and tried again with the same result. The circle never completes and if I tap on the offending track I get a “poor connection” message. I have played this track directly from Roon and it worked so something is still afoot with downloads - this was on WiFi. Oh and my phone gets very hot.
btw I juist saw another post saying ARC seems to have a problem with very long track names - the track above has a long name so maybe that’s the issue?
Thank you for the post. Did you experience this on the most recent build of ARC, just released (see here)? We’ve been making incremental improvements to download stability with each new ARC release since 2.0 came out, so we’re hoping the update will at least incrementally improve the symptoms you’re reporting.
We’ll investigate logs to see what’s happening to the track in question. Regarding long track names, we’ve yet to clarify if the long track titles or large file sizes are triggering download issues. We suspect it’s the latter but we’re actively investigating any download issues and escalating as necessary to QA, so we should have an update here shortly.
