BTW if you did the same thing with a PCM and DSD source the result is the same, but you would need an OTTO_II (or equivalent) to test that.
I'm not sure what hobbling means. I have the Buffalo III, but I swapped it for the Buffalo IIISE. You say the player is faulty, but it works fine into another Saber32 DAC🙂 Email me and I'll respond with the players and interfaces I used.
Of course it will likely work fine into a DAC wired only for DSD because it never tries to play the faulty PCM... Not sure what that proves.
if you want to wire something for only DSD, then use the B3.

All these DACs are wired to play DSD or PCM and the intent is to play both without regard to the order in the playlist.
Oh? Can you please state exactly which signals are routed to which inputs on these DACs for stereo input that support both PCM and DSD with no switching? Ours follows Dustin's directions.
Here you go:
Bit Clock / DSD Bit Clock
Word Clock (LRCK) / DSD Data Left
Data / DSD Data Right
GND / GND
Saying this as nicely as I can, that does not tell me anything. You need to describe it at the IC level.
I mis-understood the question. On test #1,#2 and #3 I used my Buffalo IIISE as is. The inputs are tied together and auto re-mapping function is on. I don't have the details on test #4 except what I wrote in the first post. He is using what you call the "faulty player" and he is not getting any POPs.
Russ, I wanted to update you on the what I found out this weekend by chance. It appears that the static burst I posted about back in April is related to DSF files that have cover art embedded in them. To test things I made up some test files with and without the cover art embedded in them and the DSF files without the cover art do not have the static bust at the end of playback...
Thanks for the update. Yes, it makes perfect sense. The DAC will play what is presented to it, and that would just be a burst of noise. Seems odd anyone would ever do that.
It's a bug and I'm expecting an update that corrects it. I appreciate your help and have been enjoying the DAC 🙂
Was the problem with the burst of static ever resolved?
I have BIIISE and have the same issue (burst of static) when a DSD finishes playing (last song only). This occurs with both A+ & HQ Player music players.

Brian - thanks for chiming in.
Yes, I saw that post (#31) but in a later post (#33) there is mention of a reported bug that needed to be fixed. It wasn't clear to me if the implied bug was related to the DAC or something else. I took it as something with the DAC needed to be fixed.
In my case, I get a pop after the last song has completed playing. This happens with all DSD files whether native DSD files (DoP) or converted PCM files (.aiff & .flac) using HQ Player. I don't have this problem when feeding DAC PCM files.
Most of my files are either CD rips using dbPoweramp into .aiff or purchased hi-rez off of one the stores (e.g. HDTracks, Acoustic Sounds). Point being all my files should be fairly standard stuff, not ripped SACD files.
In any case I would REALLY like to get this resolved so any suggestions are welcome because I would like to use DSD only.

Brian - per your suggestion, I asked Jussi Laako, developer of the HQ Player,and here is his reply:
"The pop problem is usually related to DoP and how it works. iFi just released a firmware update for their iDSD Micro to deal with this issue.
For DACs equipped with ESS Sabre it is particularly challenging. When playback stops the DAC will eventually switch from DSD back to PCM.
HQPlayer is trying to minimize the pop at this point, but in the end DAC needs to have a certain look-ahead for the incoming data to gracefully switch back to PCM mode. DAC needs to engage the output mute circuitry when switching between PCM and DSD modes.
ASIO interface helps on this front, because it doesn't change format on the fly, but instead clearly switches format before starting playback (after stopping earlier playback). So there's a clear point in time when to toggle output mute."
