Bug Description

Hello,

When loading modules, there's a problem with loading hp.pci: not found.

After that, I have no sound in hoary (totem respond: no audio output found)

I changed my kernel to 2.6.8 - i386 and everything works fine. So I'm sure the
kernel doesn't detect my sound card, wich is onboard.(today's upgrade doesn't
fix the problem, that's why I send you this bug report)

This seems to be known as a connexant id30 or Intel "82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio controller"

Don't hesitate to contact me if you want to have more information

Sorry for my much approximative english

I have the same problem. With the latest warty kernel it works but not with the
latest hoary kernel, which I need for USB 2.0. If I reload the module
snd-intel8x0, it works again but I have to do this every reboot.

dmesg:
codec_read 0: semaphore is not ready for register 0x2c
codec_write 0: semaphore is not ready for register 0x2
codec_write 0: semaphore is not ready for register 0x4
codec_write 0: semaphore is not ready for register 0x26
codec_write 0: semaphore is not ready for register 0x26

The problem exits also in Fedora Core 3 and also my modem (snd-intel8x0m)
doesn't work anymore.

Solved!

Add snd-intel8x0m to /etc/hotplug/blacklist and reboot. There seems to be a
conflict between the sound and this modem driver in this kernel version. But of
course you cannot use the modem and the alternate sl-modem driver (in
multiverse, but you need the daemon for the alsa driver anyway) doesn't work
with this kernel (it compiles but insmod fails).

Please send a copy of the contents of /proc/interrupts with both drivers loaded,
and attach a copy of your dmesg output.

Not a duplicate of #2011, but related, since #2011 also asks for
snd-intel8x0m to be blacklisted.

I have the same problem using a HP Pavilion dv1000. The sound card is the same one.

I can see also the code_write errors through dmesg.

The solution provided to blacklist snd-intel8x0m also works.

I will upload the same files after I reboot. First I'm going to hear some music ;-)

I don't know if this would help but when I installed Warty I had to pass the
kernel parameter noapic otherwise it would stall. I had no problem with sound
in that case.

When I installed Hoary from Array 4 (not upgrade) I forgot to pass that
parameter to the installer and everything worked, except for sound.

Wasn't this bug solved when you blacklisted one kernel module about a soft modem?

At least in my case, I reinstalled hoary with the final version and everything
worked (except for recording but that is for another bug report)
