systemctlサービスが起動しない

RaspBerryPi プロジェクト用のサービスを作成しました。起動しても何も起こりません。systemctl status sb.service次の結果が返されます:

Failed to start RPI-sound board.
Unit entered failed state.
Failed with result 'exit-code'.

sb.サービス:

[Unit]
Description=RPI-sound board
After=network.target

[Service]
Type=simple
Restart=always
RestartSec=1
ExecStart=/home/pi/Desktop/RPSB/RpiSoundBoard.sh
User=pi

[Install]
WantedBy=multi-user.target

実行されるはずのファイルはここでホスト自分で実行すると問題なく動作します。サービスからより多くの出力を得るには、またはこれを修正するにはどうすればよいでしょうか?
