Installation process
Hello !
This program seems pretty cool. Can you detail the installation process ? I'd like to run snapclient on an ESP32
Good job !
Hi Minard Sorry this is very much work in progress - and not working very well jet. WLAN UDP packges are not comming at a prediable flow - we do not have good time stamping on in comming packages. Stil a lot work in front of me. On the other hand if your are on wired hardware ie the wESP32 board it works. Regards Jorgen
I'd really like to make it works wirelessly! The problem comes from the esp itself ? And not from snapcast ? If I can help in any way, it will be a pleasure!
Yes the UDP wireless packet loss is not god - at least not here in my setup. Help is much appreciated. I need to back port some code to this repo and / or turn some of my common used component into sub component. Long list of todo s. What is your setup - what i2s amplifier are you using we may need to abstract that if i can not get you on my ma12070p amps. /j
Hi minard I just dusted of my setup and I get steaming audio through - not as bad as I am use to. I do get some distortion that i think ordinate from direct with to i2s driver. Will add a ring buffer. :-)
Ring buffer added - Added my dsp_processor component, another side project that added generic high level audio processing to the party. The dsp_processor is also very much in work in progress with a long feature list. Master plan will be a dynamic environment where the full audio flow can be configured and tuned from an web interface. If you want to kick in then have a look at the time stamping that is need to keep client in sync.

A web interface would be very cool ! Which sound card are you using ? also trying in WLAN ?
Yes - Did some nice progress last night. Quite stable client using WLAN - the client here is wlan only until now. I do chip design in my day time job - so i am using my own I2S input class D audio amplifier. MA12070P - We have a nice pi hat that will be a good fit for you Raspberry pi project as well. /j
Fixed major mistake - Works perfect on WLAN - rock stable. I have not implemented any buffer / throttle control - for multi room streaming that is not good. But for single point audio streaming snapcast is the best i have seen until now. /J
Ok very very nice, does the buffer part isn’t managed by snapcast ? We need to implement this in this program ?
No the snap server will just time stamp outgoing audio packages and all client are responsible to play samples at t+500ms - where the 500ms is communicated to all clients from server. Volume and mute function are passed around instantly and this gives a impression for a very responsive system.
Hi there ! I am actually trying to run your code, because it sounds pretty cool, but for now I can't hear any sound ! I guess it would be a audio format problem, what do you recommand to use ? I am on an ESP32S coupled with a PCM5102 ! I succeeded to flash your code on the ESP but can't read any sound. If you have an idea or if you know the issue, a bit of help would be really appreciated ! And i'd like to help you on this project, I think this could be great for multirooming
Hi Nathan From what i see on the data sheet of PCM5102 - you just need to keep SCK grounded and route in BCK, WS, and DATA from the ESP32 I2S interface. I use the MA12070P from Infineon - Just need to hookup I2C and I2S and it flys /J
For PCM5102 Use the setup from https://hackaday.io/project/166122/instructions by Raphael H. You need to set the correct i2s pins in the component/dsp_processor/dsp_processor.c line 60 pin_config0 I will add a menuconfig for that component - there are other cool stuff there :-)
@NathanTct did you get it up and running?
I've fiddled around a bit with the PCM5102 and an ESP32 the last few days, and seems to get it up and running, but no sound output.
