Description of problem: No sound in all applications after system update, including kernel upgrade from 4.0.8 to 4.1.2. Sound appears if I boot back into 4.0.8 Version-Release number of selected component (if applicable): 4.1.2 How reproducible: Always Steps to Reproduce: 1. Take my computer 2. Boot into 4.1.2 kernel 3. Try to play music Actual results: No sound. Expected results: Sound. Additional info: Here is the systeminfo paste - http://paste.fedoraproject.org/249371/38177215/ I use analog output of internal (AMD) chip, which uses snd_hda_intel. pavucontrol shows the music actually plays and the settings are fine, but there are no sound.
Can you give the output of: $ lsmod | grep snd
Also, do you not hear sound from only your music player? Does sound work from YouTube? Do you hear any sound when increasing the volume with the volume keys on your keyboard? (should sound like a little 'pop')
Of course I do not hear any sound, not only in music player. No system sound, no music in mp3 players, web browsers etc. here is a list of modules: [vitek@vitek ~]$ lsmod | grep snd snd_usb_audio 180224 2 snd_usbmidi_lib 32768 1 snd_usb_audio snd_rawmidi 32768 1 snd_usbmidi_lib snd_hda_codec_via 32768 1 snd_seq 73728 0 snd_hda_codec_generic 69632 1 snd_hda_codec_via snd_hda_codec_hdmi 53248 1 snd_hda_intel 32768 6 snd_hda_controller 32768 1 snd_hda_intel snd_seq_device 16384 2 snd_seq,snd_rawmidi snd_hda_codec 139264 5 snd_hda_codec_hdmi,snd_hda_codec_via,snd_hda_codec_generic,snd_hda_intel,snd_hda_controller snd_hwdep 16384 2 snd_usb_audio,snd_hda_codec snd_pcm 114688 5 snd_usb_audio,snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel,snd_hda_controller snd_timer 32768 2 snd_pcm,snd_seq snd 77824 29 snd_usb_audio,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_hda_codec_via,snd_pcm,snd_seq,snd_rawmidi,snd_hda_codec_generic,snd_usbmidi_lib,snd_hda_codec,snd_hda_intel,snd_seqdevice soundcore 16384 2 snd,snd_hda_codec I still suppose this bug is very selective to hardware. I tried to analyze and compare dmesg output for both kernels, but didn't found any suitable thing. I also checked System Settings -> Multimedia (I use KDE) for right settings, and they are there.
Even more, when I first encountered a trouble, I used a proprietary graphics driver (kmod-nvidia). I understand that this driver shouldn't affect an AMD sound chip at all, but I swapped back to open source (just to be sure) and still no sound in 4.1.2, and it is magically comes back on 4.0.8
I have also runned in problems but in my cause I was not able to use the internal mic, after disconnecting the external one. I have tried to debug pulseaudio and alsa settings, even replacing them. After that I've boot a live cd (KDE spin to keep with the current spin I use) and got everything working right, it uses the 4.0.4 kernel version.
If needed there's an alsa-info output from my machine here: http://www.alsa-project.org/db/?f=c355667dd04dd0ffef8ee4830ea13b31806e0dae
My problem does not exist in 4.1.3 kernel anymore.
