Moode Player Help

[TimCurtis]

Hi,

I was able to include the Advance Audio Kernel in the upcoming Moode 2.7 update by implementing a Kernel select feature on System config :-) Screenshots attached.

There are two kernels, Standard and Advanced. The standard kernel is a mainline Raspbian kernel which in this case is 4.4.23. The advanced kernel is based on 4.4.23 and custom built by the inmates to make 4.4.23-sc1. This kernel provide important audio capabilities as listed below. These capabilities are not available in mainline kernels.

The following are enabled via <params> supplied to the dtoverlay in config.txt

- 352.8k and 384k sample rates for es9023, pcm512x, pcm514x
- Integer bit clock divider for es9023 codec for less jitter on 48K and 96K sample rate
- DSD128 via 352.8k sample rate (either DoP or DSD -> PCM on-the-fly)
- Bypass pcm512x, pcm514x oversampling filter via 384k sample rate

And by chip type / overlay.

PCM512X, PCM514X
- 384K is automatically enabled, no param needed

PCM5102, ES9023
- hifiberry-dac,384K

PCM5102
- simple-pcm5102a-audio

ES9023
- hifiberry-dacpluslight-es9023-audio,384k,bclk_ratio_int_div
- i-sabre-dac-es9023-audio,384k,bclk_ratio_int_div
- mamboberry-dacplus-es9023-audio,384k,bclk_ratio_int_div
- es9023-audio,384k,bclk_ratio_int_div
- simple-es9023-audio,384k

ES9018
- simple-bclk-64fs
- Descr: Use a "fixed" 64fs bclk_ratio for 2 channel, 32/24/16 bit audio

MMAP (Memory Mapped I/O for I2S interface)

Memory mapped I/O is available for the I2S interface providing the Player application enables it. Currently MPD does not enable MMAP. Other players for example Squeezelite do enable MMAP.

The other new feature shown in the screen shots is improved handling of chip options for the Burr Brown family of chips including PCM514x, PCM512x and TAS5756.

Regards,
Tim

Do these new kernels improve the sound with an IQ Audio DAC+ i.e. PCM5122?
(just checked and I'm on release 2.3, which is over a year old now).

@Tim,

I reformatted the USB drive tonight - NTFS. Copied several folders of music across, plugged in and started the Rpi. Moode did not recognize the drive but the software is current set on "updating" so maybe it will show up later.

Here is the result of ls -l /media command at the moment

pi@moode:~ $ ls -l /media
total 0
pi@moode:~ $

Will get back to you later.

Hi Al,

Does this drive have a disk label?

It should show up under /media as a folder. For example I named a USB stick "VFAT-8GB". It appears under /media as

/media/VFAT-8GB

Hi,

Only your ears can determine that, but according to the inmates that developed the Advanced Audio Kernel, feeding PCM512x a 384 kHz sample rate which causes its oversampling filter to be bypassed, improves SQ.

Hi Grant,

The new features including Advanced Audio Kernel will be available in an upcoming in-place update for Moode 2.7. I'd recommend following Moode Twitter Feed if u would like latest info. Thats where I first post dev and feature information.

Hi,

Just a brief update and some updated screen shots. Thanks to one of the inmates, Squeezelite is coming to Moode :-)

Not really sure if this has been asked before or if I can even address this here with Tim, but is it possible to install / activate a equalizer so I can get some more juice out of my Audiophonics dac? Maybe via the alsaeq? Or does this not work at all with the Moode distro? Thanks
