Hello . . . I stand corrected. The newest kernel install generated sound devices. I may have to keep 5.13rc.
aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sofsoundwire [sof-soundwire], device 0: Headphone (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 2: SDW1-speakers (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 5: HDMI1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 6: HDMI2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: sofsoundwire [sof-soundwire], device 7: HDMI3 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 Entry #2 in his list generates sound through the laptop's speakers. None of the HDMI entries generate any sound. It appears that for sound, I need a newer kernel than the LTS. Thank You.
