You can try to clean up your ALSA configuration, for example, ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2212:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side are caused by /usr/share/alsa/alsa.conf: pcm.rear cards.pcm.rear pcm.center_lfe cards.pcm.center_lfe pcm.side cards.pcm.side Once you comment out these lines, those error message will be gone. You may also want … Read more
