 Posted: Sat Apr 17, 2004 7:04 pm Post subject: How to get sound working with 2 programs at same time. |
 |
|
| I want to use teamspeak while i play America's Army, but if I start teamspeak before i start americas army, i cant hear AA sounds. If i start AA first, I cant hear teamspeak sounds. This is the same with any programs that use sound. No two programs can use sound at the same time. I use ALSA and i've also tried emerging the arts thing but with no luck. Any suggestions? |

What sound card you got? The sound card on my ASUS L8400C does not work with more than one program at at time. I was using redhat 9.0 at the time, though.
However, my Turtle Beach and Audigy2 cards (not used at the same time, I upgraded) both worked fine with multiple streams. The TB only ever used alsa, the A2 switched from oss to alsa a few months ago. With both I have had something like up to 12 different instances of gqmpeg (front end for mpg123) open and playing music at the same time.
Do you get this problem only with different programs, or also when trying to get any kind of multiple sound streams?
cheers...

| I've got a VIA 8235 integrated soundcard, 2.6.5-r1 with compiled in alsa sound and yet I dont get any kind of multiple sound streams. Actually I get no sound unless I start alsasound '/etc/init.d/alsasound start' so I'm not even sure if its a kernel problem. |

The alsasound script loads modules and restores the volume. Unless you manually change the settings or have them store and restore from /etc/conf.d/local.st* then you will NOT hear any sound.

You can hear multiple sounds with mono channel sound cards if you use a sound server (esd on gnome, arts on kde). The sound server will do the mixing. But for this to work, the apps must have arts (or esd) support.
The best is to get an audigy or an sblive... you can get them cheap. These cards (as many others) suppot multiple channels. |

| Alright I think my sound card just cant handle 2 programs with sound at once and the 2 programs I want to use, dont have the ability to use esd or arts. This means I have to buy a new video card and a new sound card (because my ATI sucks on linux). |

well you can do that by adding these lines to your .asoundrc file
| Code: | 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"
}
|
hope this helps

| I didnt have an .asoundrc so I made one with the contence you specified in my home dir. I'm not really sure what this is supposed to fix tough. I still cant play 2 programs with sound at once and I'm thinking maybe this was to fix having to do rc-update alsasound. please let me know. thanks. |

| dmix works for some folks, but certain cards and programs tend to be too picky for it to work. I've spent the better part of 2 days trying to get it to work with my i820... I can play multiple ALSA streams, but OSS still pukes if anything else is using the sound card. If you can't get it working fairly quickly, then just fork over $10 for an SBLive like Jowilly said :p |

| Well im not really sure what I need to do to even try Dmix? If not - do they sell those $10 sound cards at best buy? |

the contents i posted are just a supplement to ur ~/.asoundrc file.......there are some lines there are specific to your card...... | Code: | | www.alsa-project.org |
here search for your card and u'll get a sample .asoundrc......those lines ARE ALSO required.......these just help in playing 2 sounds at the same time 
luck!

I went through the gentoo alsa guide as well as the Alsa guide for my onboard sound card (VIA VT8235) and still no luck.
here's my /etc/asound.cont:
| Code: | pcm.!default {
type plug
slave.pcm "dmixer"
}
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"
} |
and my /etc/modules.d/alsa:
| Code: | # Alsa 0.9.X kernel modules' configuration file.
# $Header: /home/cvsroot/gentoo-x86/media-sound/alsa-utils/files/alsa-modules.conf-rc,v 1.1 2003/08/05 21:07:55 johnm Exp $
# ALSA portion

alias snd-card-0 snd-via82xx
# OSS/Free portion

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##

I have the same sound system (integrated in my Gigabyte GA-7VAX mobo) and have spent days working on that. There are three ways of doing things sound with the VIA soundcard at the same time:
Programs that use ALSA will mix fine (with dmix configured as you already have done  ) like running two instances of Xmms with the ALSA output plugin.
Programs using ESD output will mix through ESD if you enable it under gnome options->sound->enable sound server at startup (haven't tested this a lot).
Programs using OSS will take over the soundcard and no more programs will be able to use it meanwhile. The only (dirty) way of getting sound is making the other programs use the 2nd channel of the VIA soundcard, with something like this:
aplay -D hw:0,1 whatever.wav
At least this way I can hear when I receive an email or some friend enters MSN while playing a game that uses OSS (as many do). Anyway sound gets distorted because of the different sample rate both programs could use (games using 22kHz, wav playing 44kHz).
Just my 2¢

Let me get this straight, if i use ESD, i dont need to have support compiled into the program? Cause the 2 programs i want to use together (Americas Army and TeamSpeak) dont have the ability to have aRts support (or ESD).
With the configuration posted above, I tried using XMMS (with alsa support) and Americas Army (that uses alsa) together and it still only had XMMS sound (cause i started it first) even though both programs use alsa. |

It helped a little but I didnt think it was as clear as it could have been. It says i need a combined playback/capture device and i did this to find out but i still dont know if i can:
| Code: | cat /proc/asound/pcm
00-00: VIA 8235 : VIA 8235 : playback 4 : capture 1
00-01: VIA 8235 : VIA 8235 : playback 1 : capture 1 |
and when i do these (its supposed to make a beep), i get static:
| Code: | cat /dev/urandom > /dev/dsp0
cat /dev/urandom > /dev/adsp |
For this, i am confused - how would i set this up for americas army?:
| Code: | Now you have to tell some games to use the playback only device (take this list as an example):
echo "quake3.bin 0 0 direct">/proc/asound/card0/pcm1p/oss
echo "quake3.x86 0 0 direct">/proc/asound/card0/pcm1p/oss
echo "quake3-smp 0 0 direct">/proc/asound/card0/pcm1p/oss
echo "wolfsp.x86 0 0 direct">/proc/asound/card0/pcm1p/oss
echo "wolf.x86 0 0 direct">/proc/asound/card0/pcm1p/oss
echo "et.x86 0 0 direct">/proc/asound/card0/pcm1p/oss

Getting static with those commands is exactly what is meant to be. You are piping the randon number generator to the sound card, so you get pseudo-white noise.
I didn't manage to work the echo /proc thing, so I cannot help you with that.
I don't play any of the two programs, but what you should try to do is to get one program (i.e. american army) playing through /dev/dsp0 ant the other (i.e. TeamSpeak) through /dev/adsp.
By default american army will use /dev/dsp so you could try firstly deleting /dev/dsp, then making the /dev/dsp0 link but naming it /dev/dsp, to use it instead of the original /dev/dsp you deleted, and finally configuring TeamSpeak to use /dev/adsp.

Damnit!
I've been trying to get this same exact thing working literally all day. I've followed the guide on setting up TEamSpeak as per the other post on this thread. /dev/sound/adsp does not produce any audio at all even with no audio devices started. Running...
| Code: | | cat /dev/urandom > /dev/adsp |
| Code: | | cat /dev/urandom > /dev/sound/adsp |
on my C-Media Electronics Inc CM8738 (rev 10) results in no white noise but runnig the test on /dev/dsp or /dev/sound/dsp works fine as long as TeamSpeak isn't already running.
I tried mapping TeamSpeak to any of the other devices listed in /dev/sound with no luck at all. Americas Army still sees /dev/sound/dsp as busy during startup no matter what device I tell TeamSpeak to use.
I even tried using the /dev/sound/dspW device I have but they all seem to actually point to /dev/sound/dsp no matter what I try. Here's the contents of my /dev/sound directory:
| Code: |
root@nightbox / # ls -l /dev/sound/
total 0
crw-rw-rw- 1 root audio 14, 12 Dec 31 1969 adsp
crw-rw---- 1 root audio 14, 4 Dec 31 1969 audio
crw-rw-rw- 1 root audio 14, 3 Dec 31 1969 dsp
crw-r--r-- 1 root root 14, 19 Jul 4 15:29 dsp0
crw-rw-rw- 1 ygreen audio 14, 5 Dec 31 1969 dspW
crw-rw---- 1 root audio 14, 0 Dec 31 1969 mixer
crw-rw---- 1 root audio 14, 1 Dec 31 1969 sequencer
crw-rw---- 1 root audio 14, 8 Dec 31 1969 sequencer2
|
dsp0 I created myself when I was trying to play around with creating alternate device but the rest were there since I installed the driver. This is what my ~/.asoundrc looks like:
| Code: |
pcm.cmipci {
type hw
card 0
}
ctl.cmipci {
type hw
card 0
}
pcm.dmixer {
type dmix
ipc_key 1024
slave {
pcm "hw: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.dmixoss {
type dmix
ipc_key 1025 # any unique value
ipc_key_add_uid true
slave {
pcm "hw:0"
period_time 0
period_size 1024 # must be power of 2
buffer_size 4096 # ditto
}
bindings {
0 0 # map from 0 to 0
1 1 # map from 1 to 1
}
}
|
I'm going insane! I've managed to get this far and the only thing I can't seem to get working is getting both of these apps to share the soundcard.
Someone help, please....  [/code] |
