I get a loud electronic sound after playing a DSD piece. It comes about 15-20 seconds after the end of the last track. I don't get a sound when switching from PCM to DSD, just the other way round.

Just to report back to say that creating a new library file appears to have removed the duplicates in the library file and allowed me to import all my playlists. I have yet to do a thorough search for duplicates, but many of the problem albums at the top of my library seem fine (touch wood). 3.5.12 seems stable so far... but only been building new library so far. The prior issues I had with memory seems to be fixed too. So too is the annoying one when the last few seconds of an occasional song were cut off.

DPS Posted June 16, 2019 Share Posted June 16, 2019 The popping noises some have described are likely to be USB noise and not an Audirvana bug. I've experienced similar issues with a similar vintage MBP over several versions of Audirvana and a bus-powered USBDAC, such as a Dragon Fly. The iFi iDefender solves this problem, so should a powered USB hub or powered DAC. Link to comment

From Audirvana the output is Ethernet cable to a microRendu, then a USPCB to the DAC. I've been using Audirvana since version 1.x and hadn't had the popping noise until the last week or so.

RunHomeSlow Posted June 16, 2019 Author Share Posted June 16, 2019 Sound like it is mechanical almost, cant describe it, but since it is just happening in Audirvana, for me it is software related. Maybe Damien can put something easy when switching from pcm to dsd when clicking randomly, i dont know. All is good when not switching between CDs...

This has no effect for my setup. I still get big pulses (and loud pops) when changing between PCM and DSD songs, whether Integer Mode is active or not. The only setting that eliminates the pulses, is selecting the option to convert DSD to PCM. Link to comment

RunHomeSlow Posted June 17, 2019 Author Share Posted June 17, 2019 Now here is the sound between a PCM track finishing whe a .DSF track is next to play as i said earlier... This sound between is not happening with JRiver or HQPlayer... so... Audirvana fault for me. two exemples where i put my iPhone at 10 inches maybe away from my speaker and recorded with the Dictaphone app. i can see my woofer and passive one bumping like a big hit. 1 Bryan Ferry finishing (16/44) with Bob Dylan (DSF) next 2 Bob Marley (16/44) finishing with Jethro (DSF) next can do it with every pcm whatever sample rate song going to a DSF song next Domicile 1.m4a Domicile 2.m4a If You Got Ears, You Gotta Listen – Captain Beefheart MacMini 2018, 4xi3 3.6GHz, SSD, 20Gb, macOS Sonoma > Audirvana Origin > Wyred DAC2 DSD Special Edition > Proceed AMP2 > Focal Cobalt 826 Signature Series > Audirvana Remote > iPhone 13 Link to comment
couchfungus Posted June 17, 2019 Share Posted June 17, 2019 Here is a scope capture, showing the pulses on the analog outputs of my Oppo UDP-205 when it transitions from a PCM song to DSD song. The upper trace (left channel) is clipped only because it goes out of range of the scope display. The pulses are sending a 350mV transient to the input of a 200 watt/channel power amp, more than enough to trigger its speaker protection relay. On a DSD to PCM transition, the pulses are the same magnitude, but with opposite polarity. Electronics geeks will recognize an RC decay, probably due to DC blocking capacitors on the Oppo's outputs. It seems that the PCM to DSD transition is causing a stationary DC offset upstream of those capacitors, which is removed with the DSD to PCM transition. Unlike RunHomeSlow's situation, my Oppo does not pass any music from the DSD song. But music resumes when I play another PCM song. Don't read too much into these scope traces. Other DACs are, no doubt, behaving differently. The Oppo has internal relays which reconfigure the filter circuitry paths for DSD and PCM inputs. The pulses that I observe may be due to these relays taking an inappropriate state. But there may be a flaw in the data stream from Audirvana which causes that error. I'm only posting this image to show what happens with this particular setup, for which Audirvana 3.5.12 is useless for playing native DSD files (unless I use the "convert to PCM option"). As noted in my earlier post, this setup includes a MacBook Pro running Mojave, and it was previously modified with the "Direct Mode" hack. If I substitute an iMac running Sierra, which has never had the "Direct Mode" hack, the killer pulses do not occur. I don't know if that implicates the hack (or previous use of the hack) as a possible cause. If Damien is monitoring this thread, perhaps he can explain what is happening, or (even better) provide a fix. Link to comment

Where is Mute During Sample Change? That's really strange. Are you changing all sample rates to one sample rate? I can't think of another reason this would be happening. No electron left behind.

Popular Post damien78 Posted June 17, 2019 Popular Post Share Posted June 17, 2019 Thank you all for these reports on PCM to DSD noise. This is something that happens with only some DAC models.

Vule Posted June 17, 2019 Share Posted June 17, 2019 Very strange. I am able to activate Audeze Reveal in Audirvana installed on MacBook Pro and I am NOT able to activate it Iin Audirvana installed on Mac mini. Does Anyone has idea what can be a problem?

RunHomeSlow Posted June 17, 2019 Author Share Posted June 17, 2019 did you installed Audirvana on another Mac before... not more then two Macs allowed...

Vule Posted June 17, 2019 Share Posted June 17, 2019 Presently I am running Audirvana 3.5.12 only on two devices Mac mini and MB Pro. A month ago I passed license from one Mac mini to this one which is in use now. Since then I haven’t tried Reveal because I was waiting for Audeze headphones to arrive. Link to comment
