play dsd file stutter on mpd+upmpdcli in ubuntu 22 or 24 LTS.

[YTSamLee]

First of all, please forgive my poor English！
1、output of “mpd --version”
2、my configuration file (mpd.conf)
3、relevant portions of the log file (--verbose)
#be clear about what you expect MPD to do, and what is actually happening

I use mpd+upmpdcli to build upnp renderer on Raspberry Pi or X86 low-power machine. play my audio file (main pcm and dsd format) on upnp server(minidlna install on ubuntu or debain);

i can play pcm and dsd audio Perfectly on debain 12( raspberry pi 4 or x86 intel atom cpu);

but On Ubuntu 22 or 24, whether the stock kernel or other low-latency or real-time kernel, playing DSD is always stuttered after a few seconds。
I want to know, can this stuttering be solved in Ubuntu?how?
mpd --version.txt
mpd.conf.txt
mpd.log

===========
Finally, I also attach the information about x86 machine on Debian
debain version.txt

My USB DAC is Holo Audio Cyan 2。
Looking forward to your recovery！

Oct 07 05:25 : exception: CURL failed: Out of memory

This is bad. Fix this first.

[YTSamLee]

How do I fix this? It's not easy for me to use alsa+mpd+upmpdcli. Do I need to program it? I'm just confused. Why is there no problem under Debian? Is it possible that I can only use mpd+upmpdcli under Debian?

[MaxKellermann]

I don't know, it's a CURL problem, not a MPD problem. This is not the right place to ask about CURL problems.
