Great, switching ALSA to Headphones works for me.
-P 70 -t 2000 -s -d alsa -d hw:Headphones -r 44100 -p 512 -n 3 -X raw

However, if I set the buffer to 256 and reboot, I’m unable to get past the Splash Screen IP error again. The only setting that seems to work is 512.

Kind regards

Hi Baggypants.
You were right, I checked my Network setup and this time I got the following.

/zynthian/zynthian-ui$ cd /zynthian/zynthian-ui; git remote update origin --prune

Hmmm…
After getting the sound card working and double checking the internet settings on the Zynthian, Iust ran the software update and now I can access Software/Repositories. That’s great.

At this moment in time then the only thing I’m not able to do is set the sound card buffer to 256.

It’s currently working like this now.
-P 70 -t 2000 -s -d alsa -d hw:Headphones -r 44100 -p 512 -n 3 -X raw

But I would prefer 256. Is this confit correct? It doesn’t seem to want to boot past the Splash Screen when I set it to this.

-P 70 -t 2000 -s -d alsa -d hw:Headphones -r 44100 -p 256 -n 3 -X raw

Kind regards

I’m seeing the same thing. Were you able to get it to 256 before? 5ms latency seems like a lot to ask from a pi.

edit: I think it’s just the onboard card can’t cope. If you set -r 22050 -p 256 -n 2 it will actually boot but the xrun warning light is on permanently. The latency for this is 11.6ms the same at -r 44100 -p 512 -n3 which seems to be telling me “This is a low as latency can get”

Also the onboard needs -n 3 otherwise it sounds like a bad tremolo effect it on.

editedit: -r 22050 -p 256 -n 3 works ok if you don’t mind it sounding a bit “Broadcast FM” but like I say, you don’t gain anything at all in latency of the default

versus

configuring for 44100Hz, period = 512 frames (11.6 ms), buffer = 3 periods

TL;DR Buy a HifiBerry DAC+

Hi Baggypants.

Yes, I believe I was. I’ll double check by flashing back to an old version I was using. Thanks a million for all your help.

Kind regards
James
