I'm using Slackware 10 and just installed it on my laptop and am now trying to get the sound working. ALSA seems to have recognized the card, but it also prints a lot of error messages to dmesg and the sound doesn't seem to work at all.

lspci shows:
00:1f.5 Multimedia audio controller: Intel Corp. 82801DB (ICH4) AC'97 Audio Controller (rev 03)

dmesg shows:
ALSA ../alsa-kernel/pci/intel8x0m.c:401: codec_semaphore: semaphore is not ready [0x1][0x700300]
ALSA ../alsa-kernel/pci/intel8x0m.c:416: codec_write 1: semaphore is not ready for register 0x54

Over and over...

If anyone knows how I can get this working, any help would be appreciated.

ethos; take a look at howtos,http://tldp.org/HOWTO/HOWTO-INDEX.howtos.html ,page 23 of 56 laptop-howto. may find answers.

Have you checked this page: http://www.linux-on-laptops.com/toshiba.html

Could be to some help.

While the laptop I have is on the list and the install seems to have been successful, there was no mention of the sound whatsoever, other than the lspci showing that it was the same audio controller that I have. I've tried over the last few days to resolve this issue, but nothing has worked. If anyone else has suggestions, I'd like to hear them.

ethos; check http://tldp.org/HOWTO/HOWTO-INDEX section 4.5.;4.5.5,4.5.5.1 audio and 4.5.5.2 video also section 5 single list howto,s
page 45 of 56pp,s; page 23 laptop howto of 56pp,s. u may find answers there too. can,t hurt but help.

Having read through those resources time and time again, they have been absolutely no help in getting this problem remedied. I even went so far as to E-Mail the guy who wrote the Linux For Laptops thing on the nearest one (it uses the same sound controller), but thus far, it's still not working.

I have a Toshiba Satellite 2450-201 with the same onboard sound as you. Have you tried to make /dev/snd/* readable/writable? I know this is basic, not very secure but hey, a lot of people have had problems getting ALSA to work - this is only one way. I'm more interested in having my sound work than having to worry about people cat nonsense to my /dev/snd/whatever.
Another approach is assigning the devices to a sound group in /etc/groups but I never had the time to investigate that approach.

If you have already solved this problem please ignore this message.

I just gave up on trying to get it working with Slackware 10. I got SUSE 9.1 Professional as that's the distribution that the Linux for Laptops guy runs and YaST recognized the card and set everything up just fine, so I think I'll just stick with using SuSE for the time being.

I'm experiencing the exact same problem with Slackware 10.0 on a Dell Inspiron 8200.

dmesg shows (over and over):
lspci shows:
The same sound card in the same laptop worked flawlessly in Slackware 9.1. Any ideas?

You wouldnt happen to have found a solution for this would you mdavidn? I have the exact same system with the exact same problem and after two nights of working with it i seem no closer than i was at upgrade.

Unfortunately not, Velda. Earlier this month, I sent Slackware technical support an e-mail with a short description of the problem and a link back here. I have not yet received a response. Perhaps you should send them a similar note.

I've been playing with the kernel. Although not new to programming, I am very new to Linux. I'll let you know if I run into a solution.

actually, i believe i solved it. Found a thread talking about ALSA trying to use the modem driver instead of sound. added snd-intel8x0m to /etc/hotplug/blacklist ran alsaconf, booted and i was rocking out to NIN half a minute later. Try it out and LMK if it helped, im working on a guide.

i have a dell 5150, with slk10. I had the same trouble, and even if i put intel8x0 and intel8x0m on the hotplug black list, it didn't work. Maybe this isn't the best thing to do, but try chmod +s artswrapper, usually in opt/kde/bin. I hope this works to you.

I'm happy to say that, after making said modification to the hotplug blacklist and rebooting, my sound worked perfectly.

Sorry jpmacias. I don't understand how it all works, but I'm guessing that the "m" means modem. Consequently, it seems to me that you should not put intel8x0 in the blacklist. Perhaps you could tell us whether the semaphore errors stopped after adding intel8x0 or intel8x0m to the blacklist.

Thanks that helped

Just some mixer adjustments and sound there is

Yeahhooo sound/internet/everything on my Toshiba Satellite 933/i830/Cirrus4299D/IHCM3 etc now with Debian 2.4 Kernel.


No end of hassle with the 2.6 Kernel were alsaconf managed to nuke my touchpad into Nirvana.
