HermesBBB-Cronus-Opus

ok ,connected everything together,no sound.as expected.what should I do?

You will want to put a cap in series (There is a spot for them already - they are included in the kit) with +Out. Otherwise you will have DC. When using an output stage like the IVY-III those cap positions can/should be shorted to get the best bass response and lowest distortion.

 

[Russ White]

ok ,I will get a Legato ASAP,i will try with noisy setup for now,which is short ground and neg and use as shield and positive for center pin of RCA,correct?

Legato will not work with Opus. You will want the IVY-III

Russ what should be the clock divider jumper position for just 22MHZ clock on board?

Any LEDs on? If you can post a photo of your setup, it might make it easier to see what's going on.

kinku: can you post photo of wiring between bbb-hermes-cronus-opus and also dip switch settings on OPUS?

1:1

Please do it on this thread though - so as to cut down on noise. 🙂

I still have the output through USB DAC, how would I change parameter for I2S out?

I just used the Botic defaults (although I have Buffalo IIs, not Opus). You have only one clock, so that's the main thing to change I reckon.

Make sure MPD is actually listening on your network interface(s). By default it will not (only localhost)

Check /etc/mpd.conf for the line with

#bind_to_address           "any"

Change to (ie uncomment):

bind_to_address             "any"

Hmm. I tried this and it still won't play nice.

In default connection settings, I've tried using the default settings and also entering the IP address of the BBB. Neither one works. 😡

I forgot you had the squeezelite version.
If all else fails, you could try mpd just to get it working.

I don't think that is the issue.as it is working through USB.

 

[miero]

kinku: GND?

 

[kinku]

GND between Opus AND Cronus connected with green cable.
how about the output ,I had to change it before
squeezelite -o hw:CARD=Pro,DEV=0

Switch setting of the Opus, which should be like below, is wrong. Please read the manual.

I2S to + (1)
DSD to - (0)
DEEMPH to - (0)
MODE to - (0)
IWO to + (1)
DIFFHW to - (0)
FSE, Mute, OSR to center (open)

 

[kinku]

Now there is white noise coming out ...better than nothing...

/sys/module/snd_soc_botic/parameters/ext_masterclk=9

/sys/module/snd_soc_botic/parameters/dai_format 16385

in uEnv.txt
optargs=snd_soc_botic.ext_masterclk=9 snd_soc_botic.serconfig=MMMM
