I have a Thinkpad T410 where, after I installed Gentoo on it, everything "just
worked (TM)". The sound is via the bog-standard Intel chips on the mobo and
uses the hda_intel drivers. I didn't use the TP for a long time, just
periodically updating Gentoo, but when I eventually did try to use it the
sound was muted. This means I shut down the X server to remove complications
from the desktop and from the console aplay doesn't produce any sound.
Everything looks normal, driver modules loaded, alsamixer shows the usual
output, channels all active. I booted to a windows partition and the sound
works, so the hardware is OK. The very weird thing is if I put the TP to sleep
with acpitool and wake it up again, the sound works for about 60 seconds and
then dies. There is nothing in the message log at all when this happens. I
upgraded the kernel but that didn't help.
This problem has been dragging on for some years and I am contemplating a
complete re-install from scratch. But before I do that does anyone have any
idea what I could try?
TIA
Robin

Which device does alsamixer or pulseaudio show as being active? I found on
some PCs that HDMI is now set as the default audio device and I had to change
the configuration to make analogue sound devices active again.

Mick, thanks for the suggestion but alsamixer still shows:
Card: HDA Intel MID │
Chip: Conexant CX20585
and is in fact the only device.

What's the output of these command lines?
(1). lspci -vnn | sed '/Audio/,/driver/!d'
(2). grep -Ei '^[^#]*(snd|hda)' linux/.config
(3). rc-update show | grep alsa
(4). grep HDA /var/log/dmesg
(5). Postinst message for alsa-utils:
pkg_postinst() {

I don't get this last part.
My ALSA is built as modules, including the core (I'm guessing that means
snd.ko, right?). I don't do anything particular to load them, they're
not listed in /etc/conf.d/modules. Yet the mixer save and restore via
alsasound works.
Could it be that alsasound itself loads the modules on demand, and the
warning above is misleading?

Did you run alsactl init to see if the alsa modules are probed and loaded
without errors?

How about checking the various volumes rather than muting maybe some
of them are 0 or rather some negative number or something? Also, you
might delete the asound.state and let the system start over. Last
resort, there is an alsa users mailing list.
One other thought, get pulse audio out of the way and see if alsa is
working.

To clarify: it works for me (TM), I don't need a solution. I am just
curious because I don't heed the warning and it still works.
My volumes are not the defaults, and they do get restored.

The warning is about old days when alsa init script loaded required
kernel modules for your audio to work. These days kernel does the
job well and it can autoload modules based on device IDs. So loading
modules by alsa init script is no longer needed in general case and
was removed.
The warning is here is for the people with special setups (e.g. out
of the tree modules) updating from very old systems.

They're listed in the output of lsmod, and sound playback works as
expected. If there was an error neither would be the case, or am I
wrong about this?

The output was what you would expect, lots info about HDA drivers and
hardware:

No output about the speakers. On another system (that works) I see:

I think Line Out is a speaker. So why the difference?

The above shows you have your laptop docked. When docked the on board
speakers are usually disconnected.

It's been a very long time since I docked a laptop and my memory is not very
reliable, but I recall fixing a similar problem by selecting a different
output device. I don't know if you can do this from alsamixer, but you should
be able to do it from pulseaudio, or from whatever GUI your desktop provides
for managing audio devices. Switch over from headphones/docking station to
speakers and you should be OK.

That's very interesting and would explain a lot except that I don't have a
dock! So does anybody have an idea as to why the TP has decided it's been
docked when it hasn't? There are not currently any other output devices to
select (AFAICT).
Thanks

It could be a hardware problem. Check the docking port has not been unlocked
accidentally for some reason, no debris is shorting its connectors and that
the BIOS menu does not report it being docked. I think the audio output
device symptom is controlled by ACPI, but before blaming bugs in ACPI I'd
start by looking at the hardware in the first instance.

The docking slot is clear, there is nothing in the BIOS about docking and
acpitool doesn't report anything about the docking state. The Dock option is
on in the ACPI section of the kernel config.
