Есть ли способ увеличить размер буфера ALSA?
При запуске этой команды:
ffmpeg -f alsa -ac 2 -i hw:1 -ar 44100 -b 64k output.mp3
Я получаю "ALSA buffer xrun" до того, как моя система заблокируется

[alsa @ 0x1c04660] ALSA buffer xrun.
Вот моя версия ALSA:
pi@raspberrypi ~ $ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.25.
Просто чтобы убедиться:
pi@raspberrypi ~ $ sudo apt-get install alsa
