 |
|
I prefer to have ALSA's dmix enabled global ly for my card and here's my working /etc/asound.conf for my nforce intel8x0 onboard soundcard :
| Code: | pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw:0,0"
period_time 0
period_size 1024
buffer_size 8192
rate 44100
}
bindings {
0 0
1 1
}
}
pcm.dsp0 {
type plug
slave.pcm "dmixer"
}
pcm.!default {
type plug
slave.pcm "dmixer"
}
pcm.default {
type plug
slave.pcm "dmixer"
}
ctl.mixer0 {
type hw
card 0
} |

Here is my .asoundrc:
| Code: | pcm.my_card {
type hw
card 0
# mmap_emulation true
}
pcm.dmixed {
type dmix
ipc_key 1024
slave {
pcm "my_card"
# period_time 0
# buffer_size
rate 48000
period_size 1024
}
}
pcm.dsnooped {
type dsnoop
ipc_key 2048
slave {
pcm "my_card"
# rate 48000
# period_size 128
}
}
pcm.asymed {
type asym
playback.pcm "dmixed"
capture.pcm "dsnooped"
}
pcm.pasymed {
type plug
slave.pcm "asymed"
}
pcm.dsp0 {
type plug
slave.pcm "asymed"
}
pcm.!default {
type plug
slave.pcm "asymed"
}
|
However I got some problems with UT (GOTY, the original version).
When I set UT to use 22001 Hz sound, sound works but it's awful.
So I set it UT to use 44100 Hz sound today, and sound was better but now the sound lags behind and stutters all the time, really weird.
I though it might have been the buffer in my .asoundrc file, but when i uncomment the buffer, i get high squeeky noises through my speakers instead of regular sound, changing the rate to 48000 didn't work (that setting is still in my posted file, I tried 44100 as well, didn't work). (I start UT with aoss ut btw).
So i'm quite stuck here, i'd love to hear xmms play during some instagib, so hopefully someone can help me here, I use intel8x0 for my soundcard (Epox 8 RDA3+ onbourd C-media 9739 chip). |

Some hints for errors like this?
| Code: | | alsa_get_mixer(): Attaching to mixer hw:0 failed: Permission denied |
xmms tells me this.... other aplications don't work too.
Did i miss something?? |

| Right, sorry. audio is the correct group. Then the only thing left to check is whether the devices in /dev belong to group audio. |

They do:
| Code: | ls -l /dev/sound
total 0
crw-rw---- 1 root audio 14, 12 Oct 13 16:04 adsp
crw-rw---- 1 root audio 14, 4 Oct 13 16:04 audio
crw-rw---- 1 root audio 14, 3 Oct 13 16:04 dsp
crw-rw---- 1 root audio 14, 0 Oct 13 16:04 mixer
crw------- 1 root audio 14, 1 Oct 12 10:45 sequencer
crw------- 1 root audio 14, 8 Oct 12 10:45 sequencer2 |
Are there any other devices i have to check?
Btw, some background info: i am running a 2.6 kernel + udev |

I keep getting errors with various programs when using aoss
as an example
| Code: |
$ aoss esd -nobeeps -terminate
esd: stack smashing attack in function read()
Aborted
|
Anyone know what causes this?
it also happens on wine
mplayer gives a segmentation fault
?? any suggestions |

In order to get this to work, forget using the integrated 2.6 kernel drivers. They just won't work no matter what you try. Just enable Sound Support (one thing) but not anything ALSA at all in the kernel config. Recompile the kernel and install the alsa-driver ebuild and set it up 2.4 style. One advantage of separate drivers from the kernel is that you can always update ALSA without upgrading your kernel in the process.
Any way is there a way to configure OSS Emulation to also be mixed in? |

I can´t second that. Works very well here with kernel-alsa.
Anyhow, maybe someone in the meantime figured out how to include enemy-territory or some game like that into dmix? Running with doesn´t work, it dies with | Code: | Received signal 11, exiting...
Shutdown tty console |
Anything else i´ve tried doesn´t work too, so i would be happy if s/o could point me a clue  |

Hi all,
I tried the solutions suggested here for software mixing (I have a Dell Inspiron 9100 with intel8x0) and everything seems to work great except for a couple of problems.
I disabled artsd (I work with KDE) and made mplayer play the system notifications. So far, so good. However, mozilla and skype refuse to cooperate. I noticed skype uses /dev/dsp. I tried running it through aoss, but then I have no microphone (I tried the asymd .asoundrc and it doesn't work). As for mozilla, I don't know where to even begin.
Thanks |

| why is it i can't hear more than two sounds at the same time? i have a default mail .wav for when evolution is evoked and I copiled it with alsa. HOwever, when i am listening to xmms and have gaim open, i hear both. Is there a remedy to this? |

that is because not all of your stuff is using alsa's default device, it might be using alsa's hw device directly, or oss emulation

why do programs access the hw device and not the default, and why doesn't the oss device map to the default device in some way? it isn't a very bullet proof system imo.

i agree, its ugly that the oss emulation doesent just wrap to the default alsa device.
and why the programs doesent use the default device as default? because the program authors somehow should be kneecapped.

Why is it even possible to use the hw directly and not the default device? isn't it the same API? If alsa makes it harder, people probably would use the defaultdeivice  Let's petition them!

you know, having to do this in Lynx
is also a pain in the ass. i keep losing it. any
way, that's another thread.
Waht was it about my post that confused
you? i thought it was pretty straigt
forward "when i reboot, i have to
do it again" i.e. the hardware mixing
process you mentioned at the beginning
of the thread. redundant: what is the
way to fix this? i'm tired of the
message that i can't start alsasound be
cause of the "lack of a soundcard", which
of course it tells me in it's own words.
i want to be able to do this whether i
reboot or not. I hope this was specific enough for you. i'm surprised
that ginven the simple language i used you could've tried to offer
and answer anyway based on maybe an idea or projection
may have had concerning the thread. /etc/init.d/alsasound restart
| Code: |
* WARNING: you are stopping a boot service.
* Unloading ALSA... [ ok ]
* Storing ALSA Mixer Levels
/usr/sbin/alsactl: save_state:1061: No soundcards found... [ ok ]
* Unloading modules [ ok ]
* Loading ALSA drivers...
* Loading: snd-intel8x0...
FATAL: Module snd_intel8x0 not found. [ !! ]
* ERROR: Failed to load necessary drivers [ ok ]
* Restoring Mixer Levels [ ok ]
|
That's the output i get. this is after doing asound.conf your way, which works, till i reaboot.
Should i have a ~/.asoundrc? or a /etc/asound.conf?
I think i'm gonna recompile the kernel with sound as a module, re-emerge all the drivers and then try again.... |

ok, where'd you go? now i can't even compile alsa-drivers. what the hell. this was working so well until i had to go ahead and reboot, but you know, it happens. i'm going back to xp. this is bullshit, i'm getting sick of this, it works, oops, then it doesn't. what the hell, anyone know why i cna't emerge alsa-drivers now?
