Alsa and snd_intel8x0

there seem to be a lot of sound problems floating around the wiki and forum, and unforutantly im going to add to them.
[im trying to show friends that linux can be a powerful multimedia editor--using hydrogen, rosegarden, cinerrala, etc. this doesn't work when i can only use one program at a time, and can't listen to music while doing anything]

i want to use alsa (not a something i have to update every 4 mounths) and am led to believe its possible. i have sound with alsa, but only with one program at a time --the wiki solution for this didn't not help.

(!) i find i can't play midi files at all

i read the links listed here and on two particular forum posts: intel and bad hardware identification and intel8x0m troubles

i do not understand the conclusion of the hardware misidentification situation, but hope that it doesnt apply

what i've got:

Re: Alsa and snd_intel8x0

You will need timidity++ and a patch set in order to play midi files (i'm assuming your soundcard doesn't have a midi synthesizer).

I don't know a lot about mixing support.  Here's a link to the official alsa doc for your sound driver.
http://www.alsa-project.org/alsa-doc/do … e=intel8x0


I have nothing to say, and I am saying it.

Re: Alsa and snd_intel8x0

As the wiki says, the dmix solution only applies to programs that use alsa, not those that are working through the oss emulation layer. This might be part of the problem.

As for the midis, this is a bit more complicated. You need to install timidity++ from extra and eawpatches from staging. Installing these two should get you going on the midis, and I think you should be able to play them on the command line with simply "timidity path_to_midi". I seem to remember some fiddling that needed to be done with the eawpatches package, but I don't quite remember right now...try a forum search, the thread is probably around somewhere.


The suggestion box only accepts patches.

Re: Alsa and snd_intel8x0

wow fast replys, thanks

kcontrol has an option to test midi (i don't use kde but was playing with arts)  i thought that'd have worked with out other packages
after pacman -S  timidity++ eawpatches
timidity fails to play the midi's i have, thought i have no way of telling if they uncorrupt files

mplayer, mpd, and gaim all work through alsa (?) .. so they should--if everything was set up right-- be able to play at the same time?

when mpd is doing its thing:

mplayer file

[AO OSS] audio_setup: Can't open audio device /dev/sound/dsp: Device or resource busy
alsa-init: got device=0, subdevice=0
alsa-init: 1 soundcard found, using: default

mplayer -ao alsa file

AF_pre: 32000Hz 2ch Signed 16-bit (Little-Endian)
alsa-init: got device=0, subdevice=0
alsa-init: 1 soundcard found, using: default

both do not do anything more than that.. no video no sound

22:27:37 [~] $ cat /etc/mpd.conf | grep ao_driver -C 3

Re: Alsa and snd_intel8x0

[put this in a new post.. because its diffrent sort of]

--i have an ibm T42 --

from http://opensrc.org/alsa/index.php?page=intel8x0   (thanks for the link above)

# this is IBM T40 specific, which
# uses the snd_intel8x0, and may
# not work on other laptops
pcm.amix {
    type dmix
    ipc_key 50557
    slave {
        pcm "hw:0,0"
        period_time 0
        period_size 1024
        buffer_size 8192
    }
    bindings {
        0 0
        1 1
    }
}

# route ALSA software through pcm.amix
pcm.!default {
    type plug
    slave.pcm "amix"
}

and

mplayer -ao alsa:device=amix foobar.mp3

doing that hangs mplayer till sound is stoped
doing it before changing asound.conf did the same as -ao alsa09
however, unlike doing alsa09 before, that works when nothing else is playing



i am confused though:
suggested changes to modprobe.conf

# ALSA portion
        alias char-major-116 snd
        alias snd-card-0 snd-intel8x0
    # module options should go here

        # OSS/Free portion
        alias char-major-14 soundcore
        alias sound-slot-0 snd-card-0
   
    # card #1
    alias sound-service-0-0 snd-mixer-oss
    alias sound-service-0-1 snd-seq-oss
    alias sound-service-0-3 snd-pcm-oss
    alias sound-service-0-8 snd-seq-oss
    alias sound-service-0-12 snd-pcm-oss

do i want the oss/free portion
does this change anything

Re: Alsa and snd_intel8x0

hehe, i'll contune to post progress in here incase someone else has this problem

suggested from the helpful link given above

alsaplayer -o alsa -d dmix file &
alsaplayer -o alsa -d dmix file &

will both play as will

alsaplayer -o alsa  file &
alsaplayer -o alsa  file &

and

aoss mpg123 file &
aoss mpg123 file &

i have the suggested (easy) ~/.asoundrc file

pcm.dsp0 {
    type plug
    slave.pcm dmix
}
# mixer0 can stay unchanged, because
# it isn't used anyway, I guess wink
ctl.mixer0 {
    type hw
    card 0

}

mplayer poop/vid/Bad Cops Between Breaths.wmv -ao alsa &

does not work..at all (it works without the &)
but

 
17:33:26 [~] $ alsaplayer music/Lawrence Arms/Lawrence Arms - 3am Qvc Shop
ping Spree Hangover.mp3 &
[6] 11175
17:33:36 [~] $ mplayer poop/vid/Bad Cops Between Breaths.wmv -ao alsa

works fine

nothing will play if mpd is playing
im confused
does anyone know what the config file for mpd should look like to allow me to play more than one thing at a time?

running hydrogen also locks up the sound, so only hydrogen can use it
i'll spend more time with it



thanks

Re: Alsa and snd_intel8x0

thats where i started, but the wiki that helped the most
http://wiki2.archlinux.org/index.php/Al … 0at%20once

i thought i had followed both those wiki instructions through (at least twice) but changing ~/.asound  to one suggested in the wiki focusing on gaim and xmms worked

i donno if i failed to notice beause i was using mpd, but xmms, gaim, and hydrogen all share fine, mpd hangs until all are stopped

hydrogen, while working, gave me some errors (besides the normal real time thing)

[ERROR]     AlsaAudioDriver     ALSA: cannot open audio device hw:0: Device or resource busy
[WARNING]   AlsaAudioDriver     [connect] Using alsa device: default
[ERROR]     AlsaAudioDriver     [connect] error in snd_pcm_hw_params_set_period_size: Invalid argument
[WARNING]   Hydrogen            [audioEngine_setupLadspaFX] m_pSong=NULL
[ERROR]     AlsaAudioDriver     Can't set realtime scheduling for ALSA Driver

and i still havn't figured out how to play the mid's hyrdogen produces


sorry for this mess of posts
thanks

yay ... sound for everything!

looking at the hyrdogen error got me to change a line in mpd.conf

Re: Alsa and snd_intel8x0

why do you have 2 dmix setups? shouldn't you only need one?

Re: Alsa and snd_intel8x0

i am having a problem with dmix and mpd and all your mpd config does it freeze it up. I have set it up to use alsa but it won't use dmix. Very frustrating. Commenting out the ao_driver_options freezes it too.

EDIT:i checked SO many times to see if anything was using the sound card. nothing. finally i rebooted just for the heck of it and it was fixed. very odd. lsof didn't show anything using any sound devs either.

Re: Alsa and snd_intel8x0

i think i can empathize with sound config fustrations

hopefully this will be helpful in some way
the whole of my (working..as far as i know) mpd config looks like this

23:09:35 [~] $ cat /etc/mpd.conf | grep -v "#"

port                    "6600"
music_directory         "~/music"
playlist_directory      "~/.mpd/playlists"
log_file                "~/.mpd/mpd.log"
error_file              "~/.mpd/mpd.error"



db_file         "~/.mpd/mpd.db"
state_file              "~/.mpd/mpdstate"


mixer_type              "alsa"
mixer_device            "default"
mixer_control           "PCM"


ao_driver               "alsa09"
ao_driver_options       "dev=default"
