@Zootalaws : My USB-Ethernet adapter is from Startech.com, using ASIX AX88179 chipset, which from this link, has driver for Raspbian since kernel 3.9.
RPi USB Ethernet adapters - eLinux.org

When I connect this one to my RPi install Moode, it is recognized by the router, but can not transmit any data from my NAS to it.

If it's recognised by the router it has been initialised.

If you have been able to configure your NAS parameters, you have obviously been able to access the UI

If you are able to access the UI, the problem isn't with moode, is it?

Logic, a great tool. You should try it.

Hi,
I just updated to 3.8.4a and wifi was not more working.

In system info, I got:
20170914 040913 worker: wlan0 exists
20170914 040913 worker: wlan0 trying SSID (Livebox-xxxx)
20170914 040913 worker: wlan0 wait 1 for address
20170914 040913 worker: wlan0 wait 2 for address
20170914 040913 worker: wlan0 wait 3 for address

investigating /etc/network/interfaces, i found:

allow-hotplug wlan0
iface wlan0 inet dhcp
wireless-power off
wpa-ssid "Livebox-xxxx"
wpa-psk "xxxxxxxxxxxxxxxxxxxxxx"

Changing "wireless-power off" to "wireless-power on" seems to fix the problem.
Was I the only one that got this bug?

I've been using MoOde now for a few weeks and love it. One technical point I'm not to sure of is, if I use the software volume control does it bit strip. It's not a deal breaker as I am extremely happy with MoOde on so many levels and have the Volume control disabled but I would like to know.

The sound does improve if you supply the DAC and Kali separately, though this entails a mod - described by Greg Stewart in the 'New Dac for RPi' thread. Soldering required though!
Jonners, could you point me in the direction of the thread about powering the Kali/Piano separately as I'm struggling to find it? When you say 'Isolator' are you talking about something like the Allo Isolator board? Is there value in running this in addition to the Kali?

Will be able to advise from there.
That's a very good idea, I'll give it a try and report back...

Yes the Allo Isolator also helps.
The thread is here: New DAC for RPI with subwoofer out (2.1 or 2.2)
Since your questions are not specifically related to Moode it might be better to continue discussions there.

Hi,

MPD's Software and Hardware volume control settings provide digital volume attenuation. The Software setting uses MPD's internal 32-bit float + dither, volume control routine. The Hardware setting results in MPD using the audio device's on-chip or on-board volume controller. AFAIK, these controllers are often basic 20 or 24 bit integer bacause they have limited compute resources. The exception might be the 32-bit float volume controller on ESS chips but unfortunately its not accessible on Linux due to ESS prohibition on Open Source drivers for their on-chip DSP functions.

Both Digital and Analog volume attenuation result in noise being added to the signal. Making the noise inaudible relative to the signal is one of the primary goals of HQ volume control. ESS has an interesting presentation on how their digital volume control works.
https://downloads.artsexcellence.nl/...me-control.pdf

Generally if you are going to use digital volume control then its best to also have a downstream analog or digital volume control so you can calibrate the entire system for lowest noise when attenuating volume. Below is how I do it with moOde and my Yamaha studio monitor system.

Assume MPD set to either Software or Hardware volume control

1) Set downstream analog or digital volume control to 0 (no volume output)
2) Set moOde volume to 100% (0dB)
3) Play a track that represents music that you typically listen to
4) Raise the downstream analog volume to the loudest level you would ever listen at

This generally results in a configuration where noise is inaudible when attenuating volume.

Btw, the calibration procedure is not exclusive to digital volume, it generally applies when using two analog volume controls for example one on an audio player and another downstream on a pre or amp.

-Tim

Default ESS volume control

Hi Tim - "The exception might be the 32-bit float volume controller on ESS chips but unfortunately its not accessible on Linux due to ESS prohibition on Open Source drivers for their on-chip DSP functions"

For interest - on one of the cheap Chinese boards sold on eBay:

ES9028Q2M ES9028 I2S Input Decode Board DAC amplifier DIY DSD IIS-32bit 384K | eBay

there is already an MCU fitted (ST's STM 8S103F3) programmed to allow access to some of the es9028 internal hardware functions (volume etc). I've soldered tact switches onto the lands already on the board and this allows the hardware volume control to be used. I think the other land allows other stuff like switching i2s input etc but I havn't played with that yet. It would be nice to work out if that volume control can be accessed and controlled using the browser volume control in Moode on the Pi..... Adrian
