I try to restart alsa, but: sudo alsa force-reload [sudo] password for jay: Unloading ALSA sound driver modules: snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-codec-generic snd-hda-intel snd-hda-codec snd-hda-core snd-hwdep snd-pcm snd-seq-midi snd-seq-midi-event snd-rawmidi snd-seq snd-seq-device snd-timer (failed: modules still loaded: snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-codec-generic snd-hda-intel snd-hda-codec snd-hda-core snd-hwdep snd-pcm snd-timer).

So I try to reinstall the driver modules in Ubuntu like this: sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa- utils lightdm ubuntu-desktop linux-image-`uname -r` libasound2 And killall the process sudo killall pulseaudio The sound card began normal work now. Also I founded a lot of error log in /var/log/kern.log like this: Jun 16 14:47:57 home kernel: [ 3494.077340] pcieport 0000:00:1c.0: AER: Corrected error received: id=00e0 Jun 16 14:47:57 home kernel: [ 3494.077357] pcieport 0000:00:1c.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e0(Receiver ID) Jun 16 14:47:57 home kernel: [ 3494.077365] pcieport 0000:00:1c.0: device [8086:a115] error status/mask=00000001/00002000 Jun 16 14:47:57 home kernel: [ 3494.077372] pcieport 0000:00:1c.0: [ 0] Receiver Error This problem occurs every time I start the computer.
