2.6.26-rc1 regression: e5e1d3cb20034a3cbcfff1f0bae12201aa2ce17e breaks artsd

[Roberto Oppedisano]

artsd (kde sound daemon) is broken on current git for my system.

git-bisect reveals the following patch as the culprit:

    fix pcspkr dependancies: make the pcspkr platform
    drivers to depend on a platform device, and
    not the other way around.

I've verified that reverting the above patch on current git fixes the
problem.

I guess you simply got the pc-speaker driver
loaded first and became your primary sound
driver, which is not what you want.

yes, that's true. Anyway in this case the sound server crashes with a
signal 6.
Passing -D dsp1 to artsd avoids the crash, but I can't hear sound coming out
from the speakers (this could be my fault, have to investigate a little
bit more).

I can't say for sure why does the
crash happen, but what is known is
that you need a very recent alsa-lib
to get pc-speaker working properly.
And  even 1.0.16 is not modern enough
for that. :(
But that's not a big deal.
The attached config is only what's
needed. Put it into /usr/share/alsa/cards
and /etc/alsa/cards and maybe that
will help. There should be already
the file with that name - overwrite it.

> Passing -D dsp1 to artsd avoids the crash,
The easiest solution is
---
options snd-pcsp index=2
---
into /etc/modprobe.conf. It will
then not go ahead of 2 other drivers
of yours.

With the supplied conf (and without the module option) artsd does not crash
anymore (no sound from pc speaker but that's not an issue, my alsa-lib is
still 1.0.16).

I can confirm that this solved any issue I had with sound, which is now
working properly.

That's rather bad. :( With the proper
config and alsa-lib 1.0.16 it was supposed
to work...
Do the speaker beeps work?
Like those made by
---
echo -e "\a"
---
command.
Have you made sure that everything
is unmuted in alsamixer and the volume
is at maximum?
If everything fails, could you please
try the "nforce_wa=1" option to snd-pcsp?
Your chipset doesn't seem to be nforce,
but who knows, maybe the nforce workaround
will help here too...

I tried the funcionality using "the other OS" and the speaker is working.

This is non working.

I believe so, but 'till now the speaker is not working.
I'll try harder.

In alsamixer i see:

Item: PC Speaker [Off]

and I cant' find a way to toggle it.
With kmix I can toggle the mute setting (alsamixer still sees it off), but
no sound comes out from the speaker.
I also tried

echo -e "\a"

without the module loaded (on old kernel), and the speaker is mute.

Probably something is wrong in my env.

I tried also this but without success.

Could you run "alsactl -f somefile store" and show that file?
This will contain the full mixer information.

When snd-pcsp is built, the input pcspkr is excluded.  So, the beep
won't work unless snd-pcsp is loaded and activated.

I tried this on 2.6.25 where:

roppedisano@poppero1:~$ grep PCSP /boot/config-2.6.25
roppedisano@poppero1:~$

So, if I'm not missing something, I think it should have worked

You turned off both "Master Playback Switch" and "PC Speaker Playback
Switch" of snd-pcsp driver.  Then it cannot work.

And, since you loaded the sound driver for on-board sound chip, you'll
likely have to adjust the mixer of that driver, too.  The beep can be
hooked to the on-board chip once after initialized.

But I'm wondering why "PC Speaker Playback Switch" and Volume don't
appear in the on-board driver.  Which codec (I suppose it's AC97) on
it?

Weird.  If CONFIG_INPUT_PCSPKR isn't there, the box shouldn't beep at
all.  If it still beeps, it must be a bug...

I tried different switch combination with  alsamixer, but no still no
sound from the speaker...
(I managed to enable the speaker, following Stas suggestion)

I can confirm that the box doesn't beep.

Both no beeps and no PCM?
Please show us your current full
mixer config again.
Please don't forget to try the
options snd-pcsp nforce_wa=1
too.

With the master volume at maximum?

If it does not even beep when issuing Ctrl-G on the shell,
you probably need to modprobe pcspkr, if it is not built-in.
(At least this is with kernels a little less
recent than 2.6.25. )

If snd-pcsp module is built, input pcspkr module won't be built...

Previously, with Stas's standalone patch, one was able to switch
between (a) no speaker (b) beep/pcspkr (c) beep/pcspkr and
PCM/snd-pcsp, all by means of modprobe/rmmod.

Now, if pcspkr is deactivated when snd-pcsp is built... I would
not get any tone out of that piece of hardware.
Except if snd-pcsp itself contains beep code, and that would
be sort of redundant when it is already in pcspkr.

Indeed snd-pcsp contains the input pcspkr code.  Yes, it's redundant,
but separating them isn't trivial.

It does contain exactly that -- snd-pcsp also provides the old input 
driver when compiled.

But now you can get any such combination
by the use of alsamixer only.

It is redundant only if you _intend_
to use both drivers. But its usually
a bad idea to have multiple drivers
serving the single device simultaneously.
The other way of thinking about it,
is that you simply use a new driver
instead of an old one. The new one
does everything the old one did and
more. Since they can't be built together,
the redundancy is then only in a source
code.
I am not saying it is an ideal solution.
It is not, but for only a single reason -
people who need only beeps, may not
want to have the entire sound subsystem
loaded. So they want pcspkr to be at
least built. But getting these drivers
back together again, suddenly became
very problematic...

I've played a little bit more with alsamixer and finally
managed to get both beep and PCM working;
nforce_wa does not make any difference with my hw.

I noticed that when I run

aplay -D plughw:2,0 /usr/share/sounds/KDE_Logout.wav

 I get a flood of:

[patch] snd-pcsp: silent misleading warning

It turns out that the buffer size you
get, is not evenly devided by period size.
18645 % 4661 = 1.
That (wrongly) triggers the warning.
This may very well be an alsa bug, or
may not, but the code in the driver is
handling that properly, so there is no
need for such a verbose warning.

The attached patch shuts down the warning.
Takashi, could you please apply?

It appears that alsa allows a sound buffer with size not
evenly devided by the period size. This triggers a warning in
snd-pcsp and floods the log. As a quick fix, the warning should
be disabled.

The right fix would be to add a hw_constraint to align the buffer
size.  The simplest way is to add the following in PCM open callback.

	snd_pcm_hw_constraint_integer(runtime, SNDRV_PCM_HW_PARAM_PERIODS);

But what does this fix? That's only a
warning, the driver itself doesn't care
at all. The fix you propose, will need
more testing, at least a confirmation
from the reporter. I simply thought this
can't happen. Now you say its a perfectly
sane situation, and then there is nothing
to care about, just shut up the warning.
No?

Well, judging from your previous comment, I thought that it's no sane
situation for *your* driver.  But if the driver doesn't care in
practice, your fix should be fine.  I'll queue it on my tree. 

thanks,

Takashi

Only by wrongly triggering a warning
that was supposed for the different
purpose. :)

Thats simple. Just press 'm' button.
There are also the M letters right
above the percentage value of the
control. That means Mute. By pressing
m, make sure no controls have M but
instead have O (not sure what does O
stand for).
You can also use F1 for help.
