Not Audirvana's Fault (was Help! Studio Skips in the Middle of Track When Streaming and Upsampling!)

Jud · March 14, 2025, 8:29pm

Studio 2.9.6 has just begun producing the following error in the past couple of days, and I can’t get it to stop (attempted remedial measures below):

When streaming at upsampled DSD rates (I’ve tried DSD512, 256, and 128), it will play only part of a track, then skip to the next. At DSD512, it skips after ~53 seconds; at DSD128, after ~3 minutes; at DSD256, after about 1 1/2 minutes.

Changing the amount of RAM devoted to the buffer doesn’t alter this at all. It occurs on every track I have tried. It doesn’t happen when not upsampling or when directly connected.

I have tried:

Switching the settings for raw PCM, fix for unwanted playback stops, and gapless mode.
Uninstalling and reinstalling Audirvana.
Uninstalling and reinstalling the remote.
Editing audirvana-studio.ini to remove everything except the EULA line, restarting the operating system, then restarting Audirvana Studio.
Running Studio on Windows and two different Linux operating systems (Xubuntu and ArcoLinux; I’ve also tried Arch, but ArcoLinux is based on Arch, so I don’t count that separately).
Changing preferences in upmpdcli regarding name of the endpoint, and whether or not UPNP AV and ipv6 are used.
Uninstalling and reinstalling mpd and upmpdcli on my UPnP endpoint.
Two different operating systems on the UPnP endpoint (Ubuntu Server, minimal Arch Linux).
Two different DACs.

None of these have changed the behavior, except that once in awhile Studio will refuse to play any part of a track at all.

@Antoine , is it possible my settings saved in the cloud could have a role, and if this is possible, can you delete those preferences so I can see whether re-entering them has any effect? The behavior began when I was experimenting with VPN software that presents a second network interface to Audirvana (I’ve since deleted it), and I wonder whether this caused a problem that continues because the settings were saved from that time.

It’s distressing to be without Audirvana at the moment, because I have really been loving the sound.

Sorry Jud, this is way out my league. Hope you’ll get it back to work

Agoldnear · March 15, 2025, 8:32pm

For what it is worth… I have no such playback behavior on macOS 15.3.2 and Audirvāna Studio 2.9.6.1 when playing native DSD128 binaural files via DoP 1.1 (USB 3.0).

Jud · March 15, 2025, 9:52pm

Yep, neither me until just a couple of days ago, and not when playing direct via USB in any case.

Amarok1969 · March 18, 2025, 4:04pm

Hi Jud, still problems? There is a new update for AS, so that might fix it?

Jud · March 19, 2025, 3:26am

Hi @Antoine -

I provided debug info in the first post in this thread, and I have the relevant portion of a session log file that I will send to the support email address, since it’s too long to copy and paste and text files can’t be attached to forum posts.

One additional piece of information is that the problem occurs when using UPnP with Audirvana running on Windows or Linux, but not when using UPnP with Audirvana running on Mac. Interesting. Again I wonder if it has anything to do with saved settings, or whether the fact that everything works fine on Mac means it’s something else.

Thanks for any help you can give.

Jud · March 19, 2025, 3:27am

Unfortunately still problems, but thank you for asking.

Agoldnear · March 19, 2025, 2:23pm

Is the disproportionality and randomness of the length of time before failure in the context of the different sample-rates, not a pointer as to what may be precipitating this behavior?

Jud · March 19, 2025, 3:05pm

Hoping so. Working on it with Antoine.

Djm1960 · March 19, 2025, 3:13pm

I think you are possibly on the right path when talking about saved settings. I recently was given a gift of Devialet Phantom II speakers. After setting up and selecting in Audirvana I suffered frequent track skipping. I had assumed that the Audirvana settings were reported by the DAC to Audirvana over UPnP however Antoine later informed me that these are just default values plugged in as they are typical of UPnP device capabilities.

Audirvana reported the DAC as 24/192 capable however research online indicated the DAC was only 24/96. Bizarrely enough I could play 24/192 tracks to the Debialet speakers but they would skip to the next track after a period, even more bizarrely other tracks whether 16/44.1 up to 24/96 would also skip. (I did not go to the lengths of timing the skips unfortunately) once I had established the DAC settings online and corrected the Audirvana settings all skipping ceased.

Maybe your settings have been corrupted at some point and that is introducing this error?

I’m an audio numpty so this comment maybe garbage but I thought I would mention it.

Jud · March 28, 2025, 5:21am

Have a spare microRendu, so I tried that. It works just fine.

Since I’ve tried installing an entirely different OS on the Fitlet3, it’s not the OS. And it’s unlikely to be the UPnP software, since I believe the microRendu uses the same.

That leaves the Fitlet3 BIOS, which I updated at some point in the past couple of months. So I’ll take a look at that.

Jud · March 29, 2025, 7:58pm

Looked at the BIOS, couldn’t see anything.

I have a spare Asus mini-PC, which I loaded up with my normal UPnP software (mpd/upmpdcli). Then I uninstalled Audirvana from the desktop, got rid of the preference and database files, reinstalled, and tried again. Same error.

So it isn’t BIOS or hardware; must be something I’ve misconfigured in mpd and/or upmpdcli. (That’s good news and bad news about the hardware. Thank goodness I don’t have to spend at least another few hundred dollars on a mini-PC that has an optical input like the Fitlet3. On the other hand, I now have to go through what may be a prolonged search into how to fix the mpd/upmpdcli configuration. I do have the microRendu to get me through, though I don’t feel the sound is quite on the level of the optical setup.)

Jud · April 7, 2025, 4:28am

Mirabile dictu, the problem has gone away with a newly updated Arch Linux install! I think the most likely reason is the update of libupnpp and/or libupnpp-bindings in the latest version of upmpdcli. A less likely possibility is that this installation of Arch is using the vanilla Linux kernel rather than the Linux-zen kernel. Whatever it is, it’s lovely to have Audirvana back on the main system!
