PMG Signature 512 DAC streamer BUG with DSD

When did it come out? Last few days?

Try it again. Sometimes it takes twice. The second usually goes fast

So there was an update. Went ok. Diff version than you posted

Changed highest setting to 512. Turned off filter and with new firmware 512 still skips. Oh well. Let’s see if you issue is solved though.

Wonder if PSA will come out with a PMG DAC without a streamer? I’m not interested in streaming, seems like there’s too many headaches to deal with.

how do we know about the update (other than thias forum)? does the DAC update automatically? still having so many glitches - hope this update solves them… sounds great though

Yeah, a couple of hours after the installation failed this new version appeared and installed without difficulty. I’ll see which of my issues have been mitigated later this morning.

Well, the latest 1f3db7 streamer firmware didn’t fix anything regarding DLNA/UPnP. I’d hoped that streaming DSF was fixed or at least tolerated, but no joy there. It still borks the streamer in random ways, some new to me, i.e., everything was shown as 48K even when it wasn’t, and the display got weird.

This is incredibly frustrating, particularly for a $9K piece of kit that advertises compatibility with DLNA/UPnP. I was counting on this working, seeing as DLNA/UPnP and Qobuz provide 99+% of my music, and have been for years. Even my eleven-year-old, original Aries Extreme streamer handles whats’s crushing the PMG streamer with ease. Can’t someone fix this, PLEASE, and test it before release?

The DAC sounds wonderful, of course, but I’ll bet a lot of >$5K DACs sound wonderful, and some (many?) of them support DSD512 and DSD1024, too. If they don’t have built-in streamers, it hardly matters to me because the one in the PMG DAC doesn’t work, so I still have to use an external streamer. I haven’t returned my DSD Mk1 trade-in yet, and I’m now actually contemplating which DAC I want to send back to the PS Audio mother ship.

This is like buying a Leatherman multi-tool where the pliers works great but the blade is chipped and dull when you really need to cut something. And, yes, I know that a Leatherman has more than two tools, so we don’t have to go there.

Yeah I get it. Did psaudio tell you it should work? Have they admitted a bug?

If so you have two choices I think. 1 is have them extend your trade in time. They offered that to me in the early stages when I bought it up. If they admit it’s bug and commit to fix it’s an option.

2 move on as you said many dac only options.

Maybe third but you seem to have balked at that is change how you stream to something that does work. If anything I think you should try it. The sound improvement in using the internal streamer is worth a try. Free trial of some software would be needed.

No, they’ve been oddly quiet. But there is a bug, which I’ve reported, regardless of any public admission.

What’s really frustrating is that most or all of the code being used for DLNA/UPnP is open-source stuff that’s been used by many others for years in their streamers. It’s not like PS Audio’s stable of programmers had to start from scratch. And turning DSF into DoP to send to the DAC, is really, really straightforward. A first-year computer science student could do it. And if that same student turned in a programming project that wrote all over itself because of unvetted input data, he or she would receive at most a C. We should be getting A-grade software, or nothing.

I’d imagine that the only really original code to be produced is whatever is needed in the back end to feed the DAC what its hardware requires. The front-end stuff just shouldn’t be that hard to get right.

I would work w Delia to get them to confirm bug. Then have them extend trade In time until fixed.

I agree. Delia is a great support person. An official ticket will put the issue on the PSAudio stack.

It is a bug. There’s no other thing it can be. The server should never crash for any reason, unless a) there’s bug, or b) there’s a hardware issue causing the server to crash.

I spoke to Delia about it at some small length over a week ago, then I left her voicemail to follow this topic. I haven’t heard anything. I guess it’s time to bug her again.

Send it back and purchase a MKll. It is an upgrade from your MKl and there are many on the market. It may be a year or two before they get the 512 right.

I swear others here use JPlay which I beleive UPnP as well. Can anyone confirm?

I’ve used JPlay for IOS with five different streamer brands and it always just works. If it doesn’t work with the PMG’s internal streamer I would look there for the cause.

That’s what I am trying to see. Is it really full blown UPnP or something else causing error. Clearly it should work. Just trying to help narrow down

I’ll continue to use JPlay for UPnP, with conversion to DoP by my server for DSF, as well as for Qobuz. I can’t play DSD256 without drop-outs, and after playing music from my UPnP server (maybe only after playing DSD256?, but I’ll experiment at some other time since it requires restarting the streamer) Qobuz Connect no longer works from the Qobuz app, but it does via JPlay.

I guess had a better night’s sleep since I’m not quite so angry about this distinctly mediocre-at-best software. I still don’t understand why it’s so amateurish after many month’s development, sort of like no one really tested it.

JPlay is certainly not the problem.

Oh, and the DSD256 drop-outs clearly aren’t the fault of the DAC hardware, since the same stuff plays as smooth as glass through my Aries streamer. The only difference is the DAC streamer rather than the Aries.

Oh shoot I meant JRiver. Your jplay shows it does not work so I was trying to ask about the Other one. I got it backwards. Let’s try again anyone here using JRiver via UPnP?

Here is what JRiver has to say about UPNP:

UPnP Server and Devices (Media Receivers) - wiki.jriver.com

EDIT: My PS Audio Sr MK1 DAC with the Bridge uses JRiver and according to the Google AI:

Yes, the
PS Audio PMG Signature 512 DAC
is compatible with UPnP (Universal Plug and Play) streaming protocols
. It includes a built-in streamer that supports DLNA/UPnP, Roon Ready, Qobuz Connect, Spotify Premium, and ShairPort connectivity.
