Choppy playback, chunks 0 frequently. High latency, #132

My playback is pretty choppy. Seems to be network related. When connecting to a station directly on my computer or phone its fine. However on the esp32 I'm getting some 0 chunks listed from time to time. Im very new to this platform and application. Would i expect network wise the connections to be of similar quality?

This issue is on all of my 5 esp32 devices, All radio stations. Bitrate ranged from ~200kbps to ~50kbps, and the chunks ranged from 300+ to 0. Ill get smooth playback on occasion for 20-40 seconds then choppy. I do some see errors in the console. I setup a hotspot with my phone, and have the same issue - but its also not that great of a connection ~20mbps

Let me know if you have any suggestions on possible problems, or if there is some "poor internet tweaks".

  1. Use local station.
  2. Increase buffer size.

The decode error is normal at the start of a new station (when using software mp3 decoder). I have no cure for the drop in the network input stream.
