v1.04 seems to be working fine here. 🙂
I noticed that when the dam is fed with DSD64, the serial port displays "L176" and with DSD128 it displays "L352", regardless of whether I'm using DoP or native DSD.
Could you add some sort of indication to show that the input signal is in fact DSD? Perhaps something like "L176D" instead of "L176".
When the dam1021 is feed DSD is will display L02M, L05M or L11M, depending on DSD speed.
When no DSD signal and the USB interface is still supplying valid clock, it will display that clock, even if nothing is playing as the dam1021 don't know nothing is being played.... At least that what my DIYINHK USB-I2S interface is doing when the DSD stream is stopped, it keep supplying the clock used when playing DSD....
Do you press enter after "+++"? I did that and it was a pain in the a*s to get connected. But since i just type +++ and wait it's working all the time.

Source lock stability seems to be vastly improved in 1.04. Previously a laptop power supply plugged into the same power board as the dam would result in frequent drop outs with spdif.
Some DSD issues here (mind you, may not be DAM-related).
DAM locks, but I hear mostly noise. If I crank the volume loud enough though, I hear the original music, though mostly overpowered by "white-noise".
My setup is:
Roon -> piCorePlayer [Squeeze] on RPI 2 -> DAM
Same file plays perfectly when Roon does the DSD->PCM conversion [DSD64 -> 352.8kHz -> 176.4kHz -> Squeezebox]
Søren, I'm so happy with your creation, that the above is mostly for you/debugging purposes.
I couldn't care less if I can't play DSD on DAM 😉
My DAM rev. 2 1.04 with Amanero plays DSD fine, but when switching between different qualities (DSD64 to DSD128 or DSD256) there are audiable cracks. Switching between same quality files is perfect without cracks.
I've just installed the 1.04 update, the locks when switching songs seems faster/better 🙂
Tested some filters: I switched life between linear and minimum phase (F4<->F6),
For me, linear is better (natural, more focused) with minimum there's something wrong with the highs, they sound more fuzzy, like a little out of phase.

So, for firmware update I just need to download 1021full_104.skr, enter the hyperterminal, connect DAM to PC, type download and update? How do I select the 1021full_104.skr file?
Thanks,

Hm, is the set filter=xxxx command working "on the fly" maybe?
I haven't tried..

Yes, I've just successfuly updated my rev.2 DAM board. I works OK! I'll try a few DSD albums.
Thanks for assistance.
Edit: when I powercycle it, it says R1.04, so I guess that's OK 🙂

Outside the uManager (temporary) by typing:
F4, F5, F6 or F7 + enter (not the function keys!)
Inside the uManager (permanent) by typing:
set filter=linear (or mixed, minimum, soft)
I have a new issue on 1.04 firmware. My DAC won't automatically switch sources between SPDIF and USB(I2S) as it was on 0.99. When both SPDIF and USB signals are available and DAC is playing from USB, when I disconnect USB cable it won’t switch to SPDIF. Power cycle is required. Then it’s playing from SPDIF. I’m connecting USB cable, start playing something by USB, then turn off SPDIF source and again – it won’t switch to USB without power cycle. I don't have source selector connected, only auto mode.
Could somebody confirm this?

I have updated FW to 1.04
Connecting Amanero Combo 384 to R2R as attachment.
Using Audirvana Plus as player ( try DoP 1.0 and DoP 1.1)
When Playing DSD content, it works fine.
When Playing PCM content, CH1 not sound, CH2 song playing with loud noise
What's wrong? My connection is correct?

Oh
connection wrong
swap green and orange at R2R make all works
Thanks my expert friends
luchoh,
I have had similar issue with RPi 2, checking the squeezelite log file showed that it was in fact sampling at a lower than expected sampling rate (48Khz) and because the RPi 2 does not have a lot of horsepower for re-sampling or high quality then one will get the "white noise".
This happened to non DSD material.
Using a PC (more CPU power) with USBtoI2S will yield much better results and >192Khz capability.
Hi all,
i bought another second / third hand DAC ("worked without any problems") and i had to realize that a cap is missing. 😡
Please can someone give the value and the "size" of this cap? Thanks!

An externally hosted image should be here but it was not working when we last tested it.
Power decoupling capacitor, not that critical, any value from 0.1u to 1u, X7R or X5R in 0603 case will do.
