初始化Jack音频服务器时出错

我想用命令启动杰克服务器

sudo jackd -r -d alsa -r 44100

但是我遇到了以下错误:

JACK server starting in non-realtime mode
self-connect-mode is "Don't restrict self connect requests"
audio_reservation_init
Acquire audio card Audio0
creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit
ALSA: Cannot open PCM device alsa_pcm for playback. Falling back to capture-only mode
Released audio card Audio0
audio_reservation_finish
Cannot initialize driver
JackServer::Open failed with -1
Failed to open server    

I tried the solutions here and here .Those Didn't work for me.

我在ubuntu bionic中使用带有Linux内核5.3的jackd版本1.9。
