I have two cards: ls -al /proc/asound/ total 0 dr-xr-xr-x 5 root root 0 янв. 30 10:52 . dr-xr-xr-x 244 root root 0 янв. 30 10:32 .. dr-xr-xr-x 3 root root 0 янв. 30 10:52 card0 dr-xr-xr-x 4 root root 0 янв. 30 10:52 card1 -r--r--r-- 1 root root 0 янв. 30 10:52 cards -r--r--r-- 1 root root 0 янв. 30 10:52 devices lrwxrwxrwx 1 root root 5 янв. 30 10:52 Generic -> card1 lrwxrwxrwx 1 root root 5 янв. 30 10:52 HDMI -> card0 -r--r--r-- 1 root root 0 янв. 30 10:52 hwdep -r--r--r-- 1 root root 0 янв. 30 10:52 modules -r--r--r-- 1 root root 0 янв. 30 10:52 pcm dr-xr-xr-x 2 root root 0 янв. 30 10:52 seq -r--r--r-- 1 root root 0 янв. 30 10:52 timers -r--r--r-- 1 root root 0 янв. 30 10:52 version
This bug probably only about Generic -> card1 So I did echo 11 > /proc/asound/card1/pcm0p/xrun_debug but after reboot it returned to 0. So I did it again and now it shows 11: cat /proc/asound/card1/pcm0p/xrun_debug 11 Where can I see detailed logs? It's difficult to provide steps to reproduce the bug. I'm just writing some php code and listening to music in Amarok. Music is mp3 files on my hard disk. I have running: netbeans, two virtualbox instances, mysql server. I have 8GB memory, but only 3.5 used (as htop shows me). Sometimes, maybe once a hour, sound begins stutter for 3-5 seconds, then it stops stutter and music continues to play normaly. Sound quality is perfect, no problems at all! Only this stutters. This bug was noticed while watching youtube. Same simptoms: video stops and sound stutter for 3-5 seconds, then continues to play normaly. Maybe some kubuntus cron jobs produce big HDD load or run with high cpu priority? Is it possible? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1274115 Title: snd_pcm_avail() returned a value that is exceptionally large Status in “pulseaudio” package in Ubuntu: Incomplete Bug description: Sometimese sound begins stutter while listen to music or watching youtube.
