2.6.26-rc5-git2: snd-emu10k1 does not work

2.6.26-rc5-git2: snd-emu10k1 does not work

[Rafael J. Wysocki]

Hi,

snd-emu10k1 doesn't work on one of my test boxes.  The driver apparently loads,
but the card is not visible, for example, to any mixer apps (including the ALSA
mixer).  However, YaST correctly detects and reports the card (the system is
openSUSE 10.3, x86-64).  The openSUSE-made kernel (2.6.22-something) does
correctly work on the same hardware.

Is there anything I should pay attention to, like any options related to /proc
or sysfs that could have an effect on the audio adapter?

Thanks,
Rafael

First off, check /proc/asound/cards whether snd-emu10k1 driver is
really loaded on the first slot.  I guess something else occupies the
position.  If yes, a simple solution is to add the following option
for snd module:

	options snd slots=snd-emu10k1

then the first slot is reserved for emu10k1.  Note that this option is
available for 2.6.25 or later kernel.

This is quite possible, as there is an on-board audio in this box too and I'm
not sure if the setup switch really turns it off.

I'll try later today and let you know.

No, it didn't work.

Here's what I got from /proc/asound/cards:

 0 [Audigy         ]: Audigy - Audigy 1 [SB0090]
                      Audigy 1 [SB0090] (rev.3, serial:0x531102) at 0xa000, irq 17
 1 [UART           ]: MPU-401 UART - MPU-401 UART
                      MPU-401 UART at 0x330, irq 10

so I think this is correct, and the "options snd slots=snd-emu10k1" thing had
no visible effect.

Then this must be OK.  Then the remaining possible problems are:

- Device files and permissions.
  Check whether /dev/snd/* files exist and have proper permissions and
  ACL (see "getfacl /dev/snd/*")

- The default ALSA configuration is hijacked, e.g. via pulse plugin.
  Try to remove /etc/asound-pulse.conf if present.

I've just installed openSUSE 11.0 on this box and the distro kernel
2.6.25.5-something works, but 2.6.26-rc8 doesn't.  The symptoms are exactly
the same as described in this thread and the kernel is the only system
component replaced.

So this is a regression from 2.6.25, actually.  Do you want me to bisect?

Hmm... there is really no visible problematic changes for emu10k1
between 2.6.25 and 2.6.26.  I guess checking /proc/asound/cards and/or
kernel config would save the time of bisect.  At least, check the
following:

1. you have emu10k1 in the first entry (#0) of /proc/asound/cards
2. the mixer states are OK (e.g. "Audigy Analog/Digital Output
Jack" switch is off, "Master" and "PCM" are muted/adjusted, etc)
3. run "aplay -Dhw:0 /usr/share/sounds/alsa/test.wav" for testing

Yes.  The contents of /proc/asound/cards are exactly as shown above.

I can only run alsamixer as root and then it works correctly.  As a normal
user it doesn't start due to insufficient access rights.

While kmix can be started as a normal user, it only shows empty window.

> 3. run "aplay -Dhw:0 /usr/share/sounds/alsa/test.wav" for testing

As root it works just fine.  As a normal user I get:

ALSA lib pcm_hw.c:1240:(_snd_pcm_hw_open) Invalid value for card
aplay: main:583: audio open error: Permission denied

I only had /etc/asound-pulse.conf .  Removed that, but it didn't change

Then I have no idea... Could you bisect?  At least, I'd like to know
whether manually built vanilla 2.6.25.x works on your system...

I tried vanilla 2.6.25 and it behaved exactly like the current -git, so this is

Still, it's interesting why the openSUSE kernels work with the card without
any problems while the kernel.org ones apparently don't.

Same config?  Particularly, same config for CONFIG_SYSFS_DEPRECATED_V2 and
other such small details?

Certainly not.

Well, in fact I'd like to find the small detail that makes the difference. :-)
