Sometimes ALSA sink does not work properly in PulseAudio. For example several emulators like Wine or DOSBox and some other programs using ALSA may cause errors similar to "ALSA lib pcm.c:8323:(snd_pcm_recover) underrun occurred" and stuttering sound. It was tolerable until recent update of RHEL to 7.5. Since the update every occurrence of such PulseAudio error increases memory used by kmix up to 50 GB (I killed process after that). Obviously it could be very many underrun occurences depending of buffer size so it looks like kmix should normally manage with buffer underrun occurences without memory leak.
Removing Usability flag. Our usability team likely cannot comment on a memory leak.
Actually this bug is extremely annoying because i've found it arose while skype-calls.
