    Question no more sound/audio after upgrading to 20.10

    Hi,

    after upgrading to ubntu 20.10 I lost audio/sound on my computer. Till then it was working greate even if 1 or 2 days after upgrade.
    I remove alsa drivers and i reinstall them but without any result.

    if i type "aplay --version" result is: v 1.2.3

    aplay -l command returns:
    Code:
    **** List of PLAYBACK Hardware Devices ****
    card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 0: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 2: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
      Subdevices: 1/1

    card 2: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 2: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 2: NVidia [HDA NVidia], device 9: HDMI 3 [HDMI 3]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 2: NVidia [HDA NVidia], device 10: HDMI 4 [HDMI 4]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 2: NVidia [HDA NVidia], device 11: HDMI 5 [HDMI 5]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 2: NVidia [HDA NVidia], device 12: HDMI 6 [HDMI 6]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    
    so basically the first device should be used. However i even do not have the sound/speaker icon in my taskbar (i user KDE 5.20).

    alsamixer returns:


    if i type: inxi -SMA
    System returns:

    Code:
    System:    Host: PC0001 Kernel: 5.10.0-051000-generic x86_64 bits: 64 Desktop: KDE Plasma 5.19.5

    Machine:   Type: Desktop Mobo: ASUSTeK model: P8Z77-V v: Rev 1.xx serial: <superuser/root required> BIOS: American Megatrends  
               v: 2104 date: 08/13/2013  
    Audio:     Device-1: Intel 7 Series/C216 Family High Definition Audio driver: snd_hda_intel  
               Device-2: NVIDIA TU106 High Definition Audio driver: snd_hda_intel  
               Device-3: Creative Live! Cam Connect HD 1080 VF0760 type: USB driver: snd-usb-audio,uvcvideo  
               Sound Server: ALSA v: k5.10.0-051000-generic 
    so i do not understand where is the issue.

    the result is the same if I use kernel 5.10, 5.9 or 5.8

    Any idea what should I check/test ?

    thx

    for an unknown reason i had to reinstall plasma-pa package like:
    Code:
    sudo apt install plasma-pa
    after that i select my audio output and it works ... weird.
