Jaunty: No sound cards any more due to broken ACL management

[Dave Morley]

Binary package hint: pulseaudio

Jaunty has no audio output available on the 20090225 daily cd this work fine on the 20090224 cd though

[Dave Morley (davmor2)]

 0 [CK804 ]: NFORCE - NVidia CK804
                      NVidia CK804 with ALC850 at irq 22

Is the contents of /proc/asound/cards

This is the output of pulseaudio when it is ran:

[Alan Jenkins (alan-james-jenkins)]

alan@alan-laptop:~$ aplay -l
aplay: device_list:217: no soundcards found...

[Alan Jenkins (alan-james-jenkins)]

output of running aplay -l as root:

[Alan Jenkins (alan-james-jenkins)]

running pulseaudio under root and then using paplay to play a sound file works. Seems to be some kind of permission change somewhere preventing normal pulseaudio users from accessing the sound cards.

To test this yourself run:

sudo -i
pulseaudio &
paplay /usr/share/sounds/question.wav

You should hear a sound.

It seems that suddenly hal's auto-ACLs got broken. I still have a ConsoleKit session, but I don't get any auto-ACLs any more, not on /dev/snd/*, and neither on /dev/dri/card0 (thus no hardware rendering any more either).

Weird, hal's ACL handling didn't really change in any way. I'll investigate.

[Martin Pitt (pitti)]

Seems the latest hal got misbuilt somehow:

Run started hal-acl-tool (20000) (0)
! full path is 'hal-acl-tool', program_dir is '(null)'

[Martin Pitt (pitti)]

This should be an alpha-5 blocker IMHO, since it doesn't just break sound, but also hardware rendering (/dev/dri), scanners, photo cameras, etc.

[Martin Pitt (pitti)]

I confirmed that a manual setfacl invocation works, and sound devices are present, so it is not a kernel bug. Also, downgrading to the previous hal makes things work again.

[Launchpad Janitor (janitor)]

This bug was fixed in the package hal - 0.5.12~rc1+git20090204-0ubuntu3

---------------
hal (0.5.12~rc1+git20090204-0ubuntu3) jaunty; urgency=low

  * 87_standalone_smbios.patch: Add missing bit from
    autoreconfiscation, which brings back the building and
    installation of hal-acl-tool. This repairs automatic ACLs, and
    thus sound card, camera, scanner, DRI, and other device access.
    Thanks to Mario Limonciello for the patch! (LP: #334299)

[ruskie (ruzkie)]

I also got hit by this, how do i fix this manually meanwhile?

[Patrice Vetsel (vetsel-patrice)]

@ruskie : Jaunty is in development and not for use. So please wait for the release of hal 0.5.12~rc1+git20090204-0ubuntu3

[ruskie (ruzkie)]

ok, i can confirm that the upload fixes this issue

[Patrice Vetsel (vetsel-patrice)]

The new iso alpha5 have the fix :
http://cdimage.ubuntu.com/daily-live/20090225.1/

[eXlin (hirvonen-henri)]

I tryed that package, downloaded it from:
https://launchpad.net/ubuntu/jaunty/amd64/hal/0.5.12~rc1+git20090204-0ubuntu3
but it didn't help with issue.

[eXlin (hirvonen-henri)]

nvm, noob me.

[Jan Rathmann (kaiserclaudius)]

Confirming that the update is fixing this on my machine.

Kind regards,
Jan

Came in and updated box this morning, now HDA intel is selectable and now works - looks like I missed this bug report and posted in an old one by mistake.

It seems I still experience this bug with hal 0.5.12~rc1+git20090403-0ubuntu1:

$ aplay -l
aplay: device_list:217: no soundcards found...

$ sudo aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC1200 Analog [ALC1200 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

[ilf (ilf)]

Hm, downgraded hal to 0.5.12~rc1+git20090204-0ubuntu3, same thing.

[ilf (ilf)]

0.5.12~rc1-0ubuntu6 and 0.5.12~rc1+git20090120-0ubuntu1 don't work either.

But adjusting the ACLs by hand fixes it:

$ aplay -l
aplay: device_list:217: no soundcards found...

$ sudo setfacl -m u:ilf:rw /dev/snd/*

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC1200 Analog [ALC1200 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

[ilf (ilf)]

I'm surry if this is rude, but it seems noone looks at this bug, so I am reopening it.

That must be a different reason, since it works for many other people.
What's the output of ck-list-sessions?

If you see something like

Session2:
 unix-user = '1000'
 realname = 'Martin Pitt,,,'
 seat = 'Seat1'
 session-type = ''
 active = TRUE
 x11-display = ':0'
 x11-display-device = '/dev/tty7'
 display-device = ''
 remote-host-name = ''
 is-local = TRUE
 on-since = '2009-04-14T06:23:08.507567Z'
 login-session-id = ''

there, in particular "is-local = TRUE" and "/dev/tty7", then please
open a new bug against hal and do the steps on
https://wiki.ubuntu.com/DebuggingHal . Thanks!
