With respect - the problem symptom may be the same, but the problem could be VERY different with a different distro/kernel. So frankly, I don’t think pointing out problems with your Ubuntu setup (and you do have at least 2 problems with that) can be applicable to openSUSE Tumbleweed. So you need to run that script with Tumbleweed.
As for your Ubuntu, may I humbly suggest you go to a Ubuntu forum for help on that. To give you a ‘leg up’ on that, you should fix your mixer setup, before you ask for help on the Ubuntu forum. Note this setting:
Simple mixer control 'Speaker',0
Capabilities: pvolume pswitch
Playback channels: Front Left - Front Right
Limits: Playback 0 - 87
Front Left: Playback 0 **[0%]** -65.25dB] **[off]**
Front Right: Playback 0 **[0%]** -65.25dB]** [off]**
Your PC has the speaker muted - so it should be clear you will not get any sound with that wrong setting in place. There are thou, likely additional issues.
Note your HDMI is card-0, and your analog sound (PCH) is card-1.
!!Soundcards recognised by ALSA
0 [HDMI ]: HDA-Intel - HDA Intel HDMI
HDA Intel HDMI at 0xf7f3c000 irq 50
** 1 [PCH ]:** HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7f38000 irq 48
By default, openSUSE multimedia applications will send audio to the sound card-0 (unless specifically configured to send sound to sound-card-1). So if this were openSUSE and not Ubuntu, that could also be an issue if you are not trying to send sound to HDMI but were trying to send sound to the analog speakers (PCH). Is this the case for Ubuntu? I do not know. I do not use Ubuntu and I have no desire to do so. So I can not in all due honesty say if the same aspect would be an issue for Ubuntu. I believe that is a clear reason why you would benefit by going to a Ubuntu forum.
Further, I note this in the dmesg, which could be specific to the Ubuntu kernel and not to the openSUSE Tumbleweed kernel:
3.532185] snd_hda_codec_realtek hdaudioC1D0: Failed to find dell wmi symbol dell_micmute_led_set
Would that failure also occur on the openSUSE Tumbleweed kernel? I don’t know.
Is that relevant to your laptop sound problem? I don’t know.
If you post again wrt the script output for openSUSE Tumbleweed , I’ll try to provide more support if I spot anything misconfigured. Otherwise, good luck on the Ubuntu forum.
… an additional note - I’m leaving Europe for a month in a day, and so I may not be checking the forum very often while out of continent.
