Question

我编写了以下代码来暂停特定应用程序的音频

spotify > '/home/user/Desktop/temp_spotify.txt' 2>&1 & # store terminal output to text file
while :
do # tail grabs recently updated last line in text file | awk searches for specific word in text and then signals exit to tail
  tail -fn0 --pid=$(pidof awk) '/home/user/Desktop/temp_spotify.txt' | awk '/spotify:ad/ { exit }'
  sleep 5
  pactl suspend-sink 2 1 # supend all audio applications grouped under sink 2
  sleep 25
  pactl suspend-sink 2 0 # resume all audio applications grouped under sink 2
done

但是我无法为pactl指定一个唯一标识符来暂停spotify应用程序。相反，我指定了sink 2，它包含许多应用程序。

如何为特定应用程序暂停音频？
