No sound on HP Pavilion dv6-1030us running 9.04

**ertayone** · June 20th, 2009

Hello,

I'm a complete Linux noob. I've gotten everything on my laptop (HP Pavilion dv6-1030us) working so far aside from the sound.

I've consulted the Ubuntu documentation Sound Troubleshooting page and here's what I've found out:

I checked Volume Control and the volume is turned up and the speaker isn't muted

The system appears to recognize my sound card. aplay -l outputs this information:

Code:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: STAC92xx Digital [STAC92xx Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

My sound modules appear to be installed. find /lib/modules/`uname -r` | grep snd outputs a long list of .ko files in the /lib/modules/2.6.28-13-generic/kernel/sound/ directory.

My sound card appears to be physically installed and recognized by my hardware. lspci -v | less lists this "Audio device:"

Code:

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
        Subsystem: Hewlett-Packard Company Device 3627
        Flags: bus master, fast devsel, latency 0, IRQ 22
        Memory at da500000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel

Here's the ALSA project's reference page for my sound setup and (I believe) the corresponding git repository page for my driver version, 1.0.18rc3. (I'm not sure why the driver version is a release candidate rather than plain old 1.0.18, the same as in the documentation. I downloaded my Ubuntu release from the official website yesterday.)

My reference page lists my ALSA module as snd_hda_intel and my soundcard codec as IDT 92HD75B3X5. The author of the documentation has found a section to match up with his codec in the git repository page, but I have not.

Where should I go from here?

Thanks in advance

EDIT: Nevermind, I uninstalled and reinstalled Ubuntu so now we are back at Square A, which is to say, ignore this reply

The problem seems to be with the Intel Corporation 82801I (ICH9 Family) audio device, which is incompatible with ALSA. I followed this guide, but it ended up fouling up everything. When I restarted alsa:

Code:

killall pulseaudio

Here's what happens when I use sudo alsa force-reload:

Code:

lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/chris/.gvfs
      Output information may be incomplete.
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/chris/.gvfs
      Output information may be incomplete.
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).

And here's what happens when I use pulseaudio -D:

Code:

I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root privileges.
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
N: main.c: Called SUID root and real-time and/or high-priority scheduling was requested in the configuration. However, we lack the necessary privileges:
N: main.c: We are not in group 'pulse-rt', PolicyKit refuse to grant us the requested privileges and we have no increase RLIMIT_NICE/RLIMIT_RTPRIO resource limits.
N: main.c: For enabling real-time/high-priority scheduling please acquire the appropriate PolicyKit privileges, or become a member of 'pulse-rt', or increase the RLIMIT_NICE/RLIMIT_RTPRIO resource limits for this user.
E: main.c: Daemon startup failed.

Now when I use aplay -l it outputs this:

Code:

aplay: device_list:217: no soundcards found...

I'm totally clueless. Is my ALPA shut off forever now?

Good news, everyone!

Nallen00's instructions in this thread got my sound working at long last. Seems to be the key for everyone with a dvX.

I've a HP HP dv4-1204TU whose sound card specifications match with yours. There is no sound in Ubuntu 9.04.I tried the steps in your last thread and configured latest ALSA snapshot. But when i give, \

sudo gedit /etc/modprobe.d/alsa-base
the output file is a blank page.
Can you help me out of this
