 Posted: Tue Oct 04, 2005 2:15 am Post subject: No ALSA sound on 2.4.26 |
 |
|
The good news is the command:
| Code: | | cat /dev/urandom > /dev/dsp |
plays loud and clear.
However, when I start KDE, it plays some start up music for a few seconds, then nothing works anymore.
Some obvious things wrong:
| Code: | | cat /proc/asound/cards |
gives "no soundcard" response.
| Code: |
amixer
Mixer attach default error: No such device |
| Code: |
alsamixer
alsamixer: function snd_ctrl_open failed for default: No such device
|
I tried "killall udevd; udevstart", which didn't help.
Some info that might be useful, although there's so much I'm not sure which to pass on:
On boot:
| Code: |
dmesg
...
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
Via 686a/8233/8235 audio driver 1.9.1-ac3
....
Mounted devfs on /dev (Is this a problem for some reason?)
....
ALSA seq_oss.c:232: can't register device seq
via-audio: ignoring drain playback error -11
|
In /etc/conf.d/alsasound I have:
SAVE_ON_STOP="yes"
ENABLE_OSS_EMUL="yes" (Added this on advice of a previous posting but it doesn't seem to have any effect)
Should I add "RESTORE_ON_START="yes"" ?
I do have a /dev/dsp pointing to /dev/sound/dsp and a /dev/snd directory.
When I run alsaconf, I get the following at the end:
...
Loading: snd-seq-oss
/lib/modules/2.4.26=gentoo-r9/kernel/sound/acore/seq/oss/snd-seq-oss.o: init_module: Device or resource busy.
Hint: insmod errors can be caused by incorrect module parameters including invalid IO or IRQ parameters.
Thanks for any help. |

| does arts work when you set it to use alsa directly (or oss emulation if you were using alsa) in control center sound system config? |

I'm using KDE 3.3.0, when I go to the "control center/sound system" there is no mention of ALSA. (Which is different than the instructions for arts in the help manual)
Under "hardware/select & configure your Audio Device/Select Audio Device" I changed it from autodetect to Open Sound System.
There is also a button to test sound, when pressed nothing happens.
So my answer I guess is "no, arts doesn't work"
But it must be more than just KDE messing it up. How is it possible that:
| Code: | | cat /dev/urandom > /dev/dsp |
works, but
| Code: | | cat /proc/asound/cards |
says "no soundcard"? |

|

I solved my problem by reconfiguring the kernel:
In Sound I unselected: "Creative Ensoniq AudioPCI 97" and "VIA82c686 AudioCode" and "VIA 82c686 MIDI"
Then selected "OSS sound modules" and "verbose initialization" and "persistent DMA buffers"
I now have sound, and alsamixer works, and /proc/asound/cards gives me my sound card info.
Two Problems remain:
1) If I go to KDE while alsa is running nothing works anymore and I need to rerun alsaconf outside KDE.
The error message I get if turning on KDE without Alsa is:
"Error while initializing the sounddriver, device /dev/audio can't be opened."
The 1 possible box to check in my KDE Control Center changing from "autodetect "to "open sound system" does nothing.
There must be a KDE config file that I can change directly to link it to the right device.
2) My 2nd problem, although the sound seems to work anyways, is :
| Code: | /etc/init.d/alsasound start
Loading Alsa driver
Using Alsa OSS emulation
Loading snd-seq-oss /lib/modules/2.4.26-gentoo-r9/kernel/sound/acore/seq/oss/snd-seq-oss.o: init_module: Drive or resource busy
Hint: insmod errors can be caused by incorrect module parameters including invalid IO or IRQ parameters.
Loading snd-via82xx
loading snd-seq
Running card - dependent scripts
Restoring Mixer Levels
|
I don't know why I have trouble with snd-seq-oss and why it doesn't seem to matter.
Thanks for any help. |

| did you build arts with the alsa use flag? It probably doesn't have the support compiled in. |
