Hi again,
can someone help me to understand a little bit more in DSD Playback? I
have three version of squeezelite here to test.
squeezelite-1.8.7-1052-debian8-x86_64 (By Ralphy)
squeezelite-1.9.0-1105-debian8-x86_64 (By Ralphy)
squeezelite-R2-deb-x86_64 (My Marco)
First one is the latest version from Ralphy.
This is the output
Code:
--------------------
sov@audioserver:~/programs$ ./squeezelite1105 -n IFI -m 00:22:4d:b7:7d:b5 -d
decode=debug -o hw:CARD=Audio,DEV=0

[11:33:14.974752] decode_flush:229 decode flush
[11:33:14.974894] decode_flush:229 decode flush
--------------------
2nd one is an older version from Ralphy. The difference here is the dsd
decoder

And the last one from Marco (also with the DSD Decoder line)
Code:
--------------------
sov@audioserver:~/programs$ ./squeezelite-R2-deb-x86_64 -n IFI -m
00:22:4d:b7:7d:b5 -d decode=debug -o hw:CARD=Audio,DEV=0

[11:35:40.470396] decode_flush:190 decode flush
--------------------
My goal would be to Play DSD natively. My IFI should be able to do this.
So when I start Marcos Version (I understood native DSD is implemented
here) and Play a DSD64 Track I get this output
Code:
--------------------
[11:38:56.063908] codec_open:218 codec open: 'd'

[11:38:56.223566] DSD_DECODE:815 DSD TO PCM OUTPUT
--------------------
So I see That it is converted to PCM. Do I have to include something
here that it is not converted?
As an option I could start with Parameter -D which would also be a
conversion of course. I can see that it is converted correctly to DOP
Code:

[11:43:13.032809] dsd_decode:544 DSD to PCM output
--------------------
With Ralphys actual release it does not Play (which make Sense as the
decoder is not implemented)
So my questions are:
- What does that Conversion to PCM mean? I thought, at least in Marcos
release there's a native DSD support. Or do we already talk about native
Playback and I misunderstand this line?
Unfortunately my IFI DAC does not have LEDs which tell what format is
played by the device.
- I would like to have the DSD decoder also registered in Ralphys latest
version. I can compile from Github however also there I do not see the
decoder included. Anything to install upfront?
Sorry for the long Post :-) If someone also interested here it might
also help hopefully.
Thanks S
