Hi I have "strange" problem with unwanted noise from built-in speaker. The noise is low and doesn't depends on volume (except off) - and it is detected only when the quiet is expected. I can disable this noise by setting volume to off or by using external speaker. This issue is detectable on pulseaudio systems - MATE, GNOME3 - fedora22, fedora23 - and I tested kernel 4.4 without any success. This issue isn't on MS Win. When I play any music, the sound system is working perfectly. Bios 2.10 01/2015, I didn't find any info about this issue, so I am writing to this mailing list. How I can help to fix it? I can run some diagnostics tools, but I have not idea, that tool I can use. Regards Pavel Stehule -------------- next part -------------- An HTML attachment was scrubbed...
