[Alsa-user] Creating 4 mono virtual devices
Hi, I have 3 devices in my notebook. hw:0,0 - internal soundcard hw:1,0 - usb soundcard hw:2,0 - pcmcia soundcard I need to create something like 4 virtual soundcards from hw:1 and hw:2 but with only 1 channel per each of them. Something like: virtual1 becomes left channel of hw:1,0 virtual2 becomes right channel of hw:1,0 virtual3 becomes left channel of hw:2,0 virtual4 becomes right channel of hw:2,0 I need that because i will be capturing 2 stereo channels at hw1 and hw2 line-ins, but I need to do separate things in realtime for each stereo channel. I tried some asoundrc configurations, but I still don't know how to do it, please help :) Thanks in advance, -- Marcin - Using Tomcat but need to do more? Need to support web services, security?

[Alsa-user] How to get a list of pcm devices
Hi, I was wondering whether there is a function to get the list of pcm devices? It would be a list which the user could choose from. I've seen that if you run aplay -L you get it, but many of those pcm devices need arguments. aplay -L just calls snd_config_search(..., pcm, ...). Is there a way to get a restricted list of just the actual devices that can be used without arguments? thanks mario - Using Tomcat but need to do more? Need to support web services, security?

[Alsa-user] Duplexing (?) Audiophile 2496
I recently installed a M-Audio Audiophile 2496 in machine running Mandriva 2006. All, including MIDI, runs just fine. But, it appears that I can only listen to a single stream at one time.

[Alsa-user] adding latency/delay to back channels in a 4.0 speaker setup
Is there a way to introduce 80ms delay/latency to the rear left and rear right channels in a 4.0 setup? I have a computer hooked up to a Samsung TV on the front channels and a stereo hifi on the rear channels. For some reason, audio seems to be delayed by the TV and a very strong echo / stadium effect is produced by default. My guess is that the TV artificially delays audio to achieve video/audio synch. With mplayer I have been able to introduce 80ms delay on the rear channels so that everything sounds just right. For that, I use the following options on video clips that contain = 4 channels (for example, ac3): -channels 4 -af delay=0:0:80:80 -mixer-channel=pcm and this for stereo files (to get sound in both front and rear): -channels 4 -af channels=4:4:0:0:1:1:0:2:1:3,delay=0:0:80:80 -mixer-channel=pcm I'd like to achieve a similar effect for other apps as well. As it is now, apps like amarok or vice do play on both front and rear even for stereo, but with this terrible echo effect. Is there perhaps a way to setup an .asoundrc and some ladspa plugins to do this? I'm running Linux 2.6.17.13 on Debian Etch with alsa-* packages versioned 1.0.11-5.

[Alsa-user] Problems under running ./configure
Hi! I have a little problem with alsa driver: I've tried to install alsa driver for an laptop shipped with Intel HDA soundcard. But when I ran the ./configure, I get this: checking cross compile... checking for directory with kernel source... /lib/modules/2.6.17.13/source checking for directory with kernel build... /lib/modules/2.6.17.13/build checking for kernel linux/version.h... no The file /lib/modules/2.6.17.13/source/include/linux/version.h does not exist. Please install the package with full kernel sources for your distribution or use --with-kernel=dir option to specify another directory with kernel sources (default is /lib/modules/2.6.17.13/source). The whole kernel source (the running kernel compiled from this) is in /usr/src/linux directory. When I set the --with-kernel=/usr/src/linux I got the same error. I checked the whole original kernel source, but no version.h in includes/linux. (2.6.17.13) What can I do? Thanks! Dchard - Using Tomcat but need to do more? Need to support web services, security?

Re: [Alsa-user] How to get a list of pcm devices
For instance, to use pcm.tee, one has to write
aplay -D pcm.tee:slave_pcm_name,file_name some_file.wav
while
aplay -D pcm.tee some_file.wav
does not work.
So if one wants to give the user a list of valid plugins, pcm.tee is not good.
cheers

}
@args.FILE {

}
@args.FORMAT {

}

[Alsa-user] recording wine output
hejhej, i bet this has already been discussed, by i am (sorry for that) too blind to find: wine is playing some sounds over the wine-oss-driver (jack driver didnt worked for me...) through my alsa-device... works fine. now i want to record this stream via arecord... what do i have to do for that? do i have to create a new plug or dmix config? i already set the capturing in alsamixer to mix (which i guess should be the playback signal...) but then a simple arecord -D default -t wav -f cd test.wav does not work: it starts put it does nothing. (which seems right to me: wine is using the device so it cannot be used from arecord same time!?) i am afraid this might be a RTFM question, but it would be lovely if someone could just post the right commmand/config... thanks mart - Using Tomcat but need to do more?
