no sound in new kubuntu breezy install, no dev/dsp file!

set235 · 03-17-2006, 03:44 PM

just installed kubuntu 5.10 breezy and cannot get the sound working. there is no /dev/dsp at all.

i am using built in sound on my mother-board
it is an Asus k8u-x board with

here's what lspci shows:
0000:00:04.0 Multimedia audio controller: ALi Corporation M5455 PCI AC-Link Controller Audio Device (rev 20)

that should be my built in sound chip, right?

lsmod|grep snd shows:
snd_intel8x0 30144 0
snd_ac97_codec 72188 1 snd_intel8x0
snd_pcm_oss 46368 0
snd_mixer_oss 16128 1 snd_pcm_oss
snd_pcm 78344 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer 21764 1 snd_pcm
snd 48644 6 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore 9184 1 snd
snd_page_alloc 10120 2 snd_intel8x0,snd_pcm

if i try ls -l /dev/dsp* i get:
no such file or directory

if i use konquerer to look in /dev, there is no dsp file.

from what i can tell, all alsa packages i can see are installed, i even removed and re-installed each package. seems that some others have had this issue with no dsp file on the kubuntu forums however noone seems to have a solution. i tried MAKEDEV but since i dont know what i am doing there, it did not work, seems like it just created a blank generic device file. not real sure what to do from here, any help would be much appreciated.

try 'modprobe snd-intel8x0' then alsamixer to turn up volume levels and unmute all controls. use 'alsactl store' to save settings.. let me know if this works and if not the output at any stage

set235 · 03-19-2006, 11:27 PM

well, the modprobe returns nothing in terminal, and the alsamixer returns :
alsamixer: function snd_ctl_open failed for default: No such file or directory

some more info....
i tried to use ubuntu 5.04 hoary and sound worked just fine, i then upgraded to 5.10 breezy and the sound is no longer working. seems that the sound will not work with clean install or upgrade.

set235 · 03-19-2006, 11:29 PM

in case you are wondering why i dont just stick with 5.04 hoary, java issues, i want to be able to use blackdown java and it doesnt like hoary.

nadroj · 03-19-2006, 11:31 PM

did you do the alsamixer command, after you did the modprobe command?

if you did, and it still gave the error, then the proper driver probably isnt loaded for the sound controller... try 'modprobe snd-ali5451' then alsamixer.. does alsamixer still give errors?

set235 · 03-19-2006, 11:37 PM

modprobe snd-ali5451 gives this error:
FATAL: Error inserting snd_ali5451 (/lib/modules/2.6.12-9-386/kernel/sound/pci/ali5451/snd-ali5451.ko): Operation not permitted
FATAL: Error running install command for snd_ali5451
then alsamixer gives this
alsamixer: function snd_ctl_open failed for default: No such file or directory

yeah, i ran alsamixer after the modprobe commands.....so drivers possibly? asus seems to be no help with this as i cant find linux drivers for my board

nadroj · 03-19-2006, 11:39 PM

did you run the modprobe command as root?

set235 · 03-19-2006, 11:46 PM

ahh, running modprobe snd-ali5451 as root gave no error, just the next line, still getting the same alsamixer error though

nadroj · 03-20-2006, 12:06 AM

what is the output now (after you modprobe'd those 2 modules i have mentioned) of 'lsmod'?

what is the output of 'cat /proc/asound/cards' i think is the file.. if not look around in that folder for something similar.

the snd-intel8x0 or snd_intel8x0 module should work.. it says in the source code that your card is supported.

Code:

 49 MODULE_SUPPORTED_DEVICE("{{Intel,82801AA-ICH},"
 50                 "{Intel,82901AB-ICH0},"
 51                 "{Intel,82801BA-ICH2},"
 52                 "{Intel,82801CA-ICH3},"
 53                 "{Intel,82801DB-ICH4},"
 54                 "{Intel,ICH5},"
 55                 "{Intel,ICH6},"
 56                 "{Intel,ICH7},"
 57                 "{Intel,6300ESB},"
 58                 "{Intel,MX440},"
 59                 "{SiS,SI7012},"
 60                 "{NVidia,nForce Audio},"
 61                 "{NVidia,nForce2 Audio},"
 62                 "{AMD,AMD768},"
 63                 "{AMD,AMD8111},"
 64                 "{ALI,M5455}}");

set235 · 03-20-2006, 12:19 AM

lsmod now shows this:
snd_intel8x0 30144 0
snd_ac97_codec 72188 2 snd_ali5451,snd_intel8x0
snd_pcm_oss 46368 0
snd_mixer_oss 16128 1 snd_pcm_oss
snd_pcm 78344 4 snd_ali5451,snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer 21764 1 snd_pcm
snd 48644 7 snd_ali5451,snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore 9184 1 snd
snd_page_alloc 10120 2 snd_intel8x0,snd_pcm
i think this is all that is there dealing with sound, the
cat /proc/asound/cards command gives
---no soundcards---

nadroj · 03-20-2006, 12:24 AM

as root run the commands again

Quote:

modprobe snd-intel8x0

then paste here the output of 'lsmod'.. also give alsamixer a shot again

if still not working then 'modprobe snd-ali5451' instead and try again.

the reason i say to insert these 2 modules again is because the 'lsmod' output you gave me gives 'snd_...' not 'snd-...' so try inserting them and make sure you use '-' not '_'

hope you get it to work.

btw, thanks for all the help, even if i dont get it working!!

nadroj · 03-20-2006, 08:36 AM

try, as root, to see if the file even exists.. because i still cant see it in the output

Code:

find / -name "snd-intel8x0*"

set235 · 03-20-2006, 08:21 PM

here's what i get running find as root
/lib/modules/2.6.10-5-386/kernel/sound/pci/snd-intel8x0.ko
/lib/modules/2.6.10-5-386/kernel/sound/pci/snd-intel8x0m.ko
/lib/modules/2.6.12-9-386/kernel/sound/pci/snd-intel8x0.ko
/lib/modules/2.6.12-9-386/kernel/sound/pci/snd-intel8x0m.ko
the first 2 entries i assume are from the pre-upgrade kernel (sound worked fine then)
