OK... my aplay -l is
--- Code: ---**** List of PLAYBACK Hardware Devices ****
card 1: PCH [HDA Intel PCH], device 0: ALC3232 Analog [ALC3232 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
--- End code ---
Which is what it was before, if I'm not mistaken.
I manually tried (in terminal, not bootlocal.sh):
--- Code: ---modprobe -r snd_hda_intel
modprobe snd_hda_intel options model=tpt440
--- End code ---
But I was not able to get any sound from speaker-test and got the same kind of errors I had before.
The really weird thing is there seems to be no card0...
I dug around a bit in my sys/ filesystem. i have these:
/sys/module/snd/ /sys/module/snd_hda_intel/
/sys/module/snd_ctl_led/ /sys/module/snd_hwdep/
/sys/module/snd_hda_codec/ /sys/module/snd_intel_dspcfg/
/sys/module/snd_hda_codec_generic/ /sys/module/snd_pcm/
/sys/module/snd_hda_codec_realtek/ /sys/module/snd_timer/
/sys/module/snd_hda_core/
I tried to look around, but I don't see anything that is claiming to be card0. I do see a rat's nest of symlinks that recurse in a crazy way. ???
Not getting much further with ALSA, I'm afraid! Thanks for the links... maybe I can get some more clues from them.

but what you are focussing on is to get sound ....and I accept if my method half succeeds, lets not worry about index=0 and instead,
if you like....install pulsaudio and pavucontrol....read their info files.
pavucontrol will allow you to swap your preferred output device. Maxmise the GUI so you can see all the TABS

I suppose I can try PulseAudio tomorrow or the next day!

Hi
no card0? the hardware data submitter had such so weird!
I have a new link for you to study and curaga hinted at solution too
--- Quote ---have you installed the thinkpad-acpi extension? It's unlikely it affects sound, but being thinkpad-specific would be good anyway.
--- End quote ---
For the moment I think its safe to have this in your boot list if curaga agrees?
to be rude....it NOW must be installed to have relevance below solution to try
2) Do this all by commands---we can sort it out later scripts/boot list and other configs later
so remove all sound packages (except thinkpad) and media players from your boot list please
Read link
https://github.com/xbelanch/Arch4T440P/blob/main/arch_4_t440p_installation.md
Notice that they are loading alsa-utils alsa-plugins alsa-lib pavucontrol
so we will do the same but in a different order due to dependencies
--- Code: ---tce-load -i alsa-config alsa-plugins pavucontrol
--- End code ---
When you look at our deps...alsa-config contains alsa-utils
alsa-plugins has deps including alsa & libasound plus others
pavucontrol has dep of pulseaudio
Next we become root for these comands
--- Code: ---sudo su
modprobe -r snd_hda_intel
modprobe snd_hda_intel options enable=0,1 index=0
modprobe -r snd
modprobe snd options slots=snd_hda_intel, thinkpad_acpi
modprobe -r thinkpad_acpi
modprobe thinkpad_acpi thinkpad_acpi index=1
--- End code ---
Warning I have never done a parameter for snd kernel module so not sure if it works without a removal and modprobe
next run
--- Code: ---aplay -l
--- End code ---
as hinted by curaga, its possible if you had that thinkpad module loaded, it was stealing card0 slot
do we have card0?

YES! There were a few issues in the modprobe commands (see below), but at the end of it, I have a card0 and I could run the 'speaker-test [-Ddefault:1] -c2 -t wav -l1' test and hear sound! Thanks!
Now, I need to figure out what was necessary in these commands to make it work. Pulling in PulseAudio or maybe just some of the modprobe commands are needed to sort out the device drivers, or perhaps almost all of it. I'll study the link you included to understand things a bit better.

I suspect that may be a typo. I think it should probably be:
--- Code: ---root@box:/home/tc# modprobe thinkpad_acpi index=1
--- End code ---

Ahh, that makes more sense, especially now that I've skimmed the linked blog for an Arch install on a T440p. The typo must not be fatal, but perhaps setting that correctly will help with other machine-specific things, so I'll update and set it correctly in my bootlocal.sh script.
Before this last change, I put the other modprobe commands in my bootlocal.sh script and re-installed alsa-config.tcz, alsa-plugins.tcz, pulseaudio.tcz, and pavucontrol.tcz and set those to be loaded onboot. I'm able to reboot now and have sound working! Speaker-test works and I can play Youtube vids in FireFox and hear their audio. The PulseAudio VU Control app allowed me to change the volume.
So, overall, I think my issue is solved! Thanks @Rich, @aus9, @curaga, and @vinceASPECT to jumping in to help me!
Can I edit the title of the thread to show SOLVED? I don't see a way to edit that (so far).
