There is only signals transmitted with standard Ethernet, through as Phofman said an isolation transformer and common mode chokes. Also how the interface is laid out and where all the relevant components go (transformer, caps, usually ESD protection diodes etc) are all designed to create an interface that works whatever it is plugged into, and an important aspect of this is avoiding noise, from either side of the connection, so I would not worry.

Hi Soundchek,

I'm asking your help installing Squeezelite on a SB Touch with USB Amanero Combo384.

So far I installed EDO plugin and got sound through Amanero USB into my DAC up to 192Khz.

I downloaded squeezelite-armv6 and your script (from Squeeze-me-lite Appendix 2 - your site) and configured LOCALETHERNETPORT, SERVERIP but have problems with setting AUDIOIF because squeezelite -l lists only "null" so the connected USB soundcard is not recognized by squeezelite.

Am I missing a configuration step so squeezelite can see my USB DAC?

Thanks,
Zsolt

l.e. just found the squeezelite thread on slimdevices...

Type

cat /proc/asound/cards


that'll show you the recognized devices.

If you see the USB DAC

you can configure it according to ALSA terminology

hw:0,0

for DAC 0

hw:1,0

with squeezlite

forget that -l option.


You might also install one of Triodes tweaked kernels on top of EDO.


Good luck

Got it working, partially... as it still has the "head". If jive is killed then the Touch restarts in 4-5 seconds. Any idea why?
I use version 7.7.2 - if this info is of any use.

I'm also aiming to stream at 352.8Khz - through SoX upsampling - and this seems to work if I connect the Amanero Combo384 to the PC which hosts the Logitechmediaserver and a Squeezelite (tried on Windows 7) but when Squeezelite is on Touch (probably anything then localhost) it does not upsample only up to 192Khz.

I remember you said that for 352.8/384K Logitechmediaserver has to be patched. How is this patching done?

Thanks.

Hi.

The watchdog kicks in if you kill jive. That's why the Touch restarts.

You need to disable (comment out) the watchdog in /etc/init.d/rcS

The Touch has a pretty poor usb implementation. I doubt that you're
getting fun with your super HiRez stuff.


Cheers

Try google.

I guess I won't ever use 384khz material.

Directly me neither, 90% of my music is 44k1 but I'm upsampling to feed my NOS DAC since I don't want the bats to party around my house.

I was looking for a standalone digital filter implementation that can do minimum-phase (apodising) filter-response but "classic" ICs - DF1706, SM5847, PMD100 - cannot, and the DSP way is not an option _for me_ since I cannot afford that much time for learning. My only option for this was to upsample offline or on-the-fly on the server and brute force use network bandwidth to stream data. I will probably end up with a fan-less PC running both LMS and Squeezelite.

BTW. I got 352K8 working with Squeezelite on Touch and sound-wise seems OK, can hear no drops. Will start it in debug mode to check if everything is OK though.


Can I use your TT 3.0 toolbox with EDO and Squeezelite to stop things like: WLan, IR, screen-off?

Thanks, Zsolt

If you run squeezelite you don't need EDO. EDO mainly addresses the jive
related stuff. And jive is not (shouldn't be) running if you run squeezelite.

Basically you can run TT3 and on top you run squeezelite.
You might run one of those EDO kernels, which come with a
slightly tweaked usb audio driver.

I have a SB3 and have read that replacing the PSU can improve it a little. I am thinking of getting a Power One HB5-3/OVP-AG. I assume this would be fine and would certainly be no worse then the stock one?
Anybody used one?
Thank you.
