alsa-util.c: Function snd_pcm_avail() returns a value that is extraordinarily large: 370196 bytes (2098 мс).

An old issue with ALSA is still present in Ubuntu 16.04.6.
The system became extraordinarily slow and hangs at total in around a minute while playing a music (around a few hours in my case).
