I have tried all the available AHCT595 TI, Phillips, NXP, Nexperia, Diodes.
The fact that Nexperia is different from the NXP discovered quite recently.
The new Nexperia has lower consumption than NXP. SNR worse by 3-5db.
I believe that you do not need to re-install already installed Nexperia. By ear, you will not notice this difference.

Find Phillips or NXP is difficult now. Remains of NXP still exist in some warehouses. But to search you need to make an effort.
I had a stable supplier Phillips, but I cleared his entire warehouse.
Try searching on TaoBao. In the warehouses of China NXP you will find. Do not worry about fakes. These ICs are not profitable to
counterfeit.

I thought I would have the best of both worlds by installing Pavel's latest botic version (downloadable from here https://puredsd.ru/) with HQP NAA and Roonbridge on my BBB eMMC and his stripped down version bootable from uSD card. The stripped down version works fine from uSD but I can't get the NAA/Roonbridge version to boot at all. I've tried copying the image with Etcher and also Win32DiskImager; both seem to copy the image. Has anyone else had any success?

I will write to SD and check again this archive. Perhaps there was somewhere a mistake when packing in gz.

I checked the file again http://puredsd.ru/Arch_Botic_DSC2.gz
Recorded with Etcher on 8Gb SD.
And checked the successful launch on BeagleBone Black and Green.

Thanks Pavel. I'll give it a try again.

I updated my HQPlayer install earlier and notice a new control app listed on the Signalyst website;


HQPDcontrol - Apps on Google Play


as an Android user and not yet being a Roon subscriber I installed it and tried it out. I'm still working out my way around the menus but it's simple to use and works very well as a no-frills network controller for HQPlayer. You can select and play music from the HQPlayer library and remote volume control works if you have it enabled. Worth looking at if your situation is similar to my own.


I've been using Muso but I've now uninstalled it.

Hi Pavel. There was never anything wrong other than my own misunderstanding; I assumed that the absence of any flashing LEDs on the BBB meant that the boot was failing when it was in fact working everytime. I hadn't realised that you have disabled the LEDs in your image. So sorry to have troubled you.



It's all working fine now but a couple of questions;


  • I notice that you set option snd_soc_botic.ext_masterclk to 7 but I couldn't find a reference to a value of 7 on Miero's botic web page? I have changed this setting to 3.
  • Why are you setting the serializers to MM-- and not DD--? I've changed the setting to DD--.

Cheers


Ray

7 instead of 3 for simultaneous compatibility Amanero/BBB on my new version of DSC2.
I am using a DSDon signal. If DD is set, then DSDon is always "1".

Pavel,
do you have a substitute for AHCT595, because I could not find Philips or NXT.
Thank you
