Hi, I found this message into my kernel logs this morning and it is said that I shoud report it to ALSA developers. Sorry, it is French. I'm going to try to translate it : 1800 Dec 24 08:22:20 phlsys pulseaudio[2291]: ALSA nous a réveillé pour écrire de nouvelles données à partir du périphérique, mais il n'y avait en fait rien à écrire ! 1801 Dec 24 08:22:20 phlsys pulseaudio[2291]: Il s'agit très probablement d'un bogue dans le pilote ALSA « snd_usb_audio ». Veuillez rapporter ce problème aux développeurs d'ALSA. 1802 Dec 24 08:22:20 phlsys pulseaudio[2291]: Nous avons été réveillés avec POLLOUT actif, cependant un snd_pcm_avail() ultérieur a retourné 0 ou une autre valeur < min_avail. 1800 ... ALSA wake us up to write datas from the dev but there was nothing to write ! 1801 ... This is probably a bug within the ALSA driver "snb_usb_audio". Please report this issue to the ALSA developers. 1802 ... We were waked up with an active POLLOUT however a previous snd_pcm_avail() returned 0 or an other value < min_avail. I'm running 3.16.0-7-amd64 #1 SMP Debian 3.16.59-1 (2018-10-03) x86_64 GNU/Linux Please find attached my hardawre list. While I'm at it, I also tried to register to www.*alsa*-project.org without success because I might be able to bring my computer skills to that project even if my skills regarding any sound server are very low.
