gtick sharing the sound card with other apps

sycamorex · 09-30-2007, 05:42 AM

Hi,
Whenever any application that uses sound (be it amarok or youtube website) is running, gtick (metronome) is not able to produce any sound (I got the following error: '/dev/dsp is busy'). I need to turn off anything using sound and then gtick will work properly.
I assume it's not the soundcard fault (it's audiophile 2496 and it doesn't have any problems with other music apps running simultaneously). It'll be a gtick problem.
I don't know, can I change something in gtick?
thanks

EDIT: the only place in gtick preferences that may matter is:

Quote:

sound device: /dev/dsp

and that's it

Hi sycamorex, Lets see if the OSSEmulation modules are loaded. Please post the output from the following.

Code:

/sbin/lsmod | grep snd

We are looking for these modules, snd-pcm-oss, snd-mixer-oss, snd-seq-oss. If they are loaded have a look here for some help.

http://alsa.opensrc.org/index.php/Aoss

The gtick page suggests that oss compatibility is needed for this to work.
Good luck. ;-)

Thanks for your reply,

alsa docs say that there are 2 ways of emulating oss
1. by loading snd-pcm-oss, snd-mixer-oss, and snd-seq-oss modules into the kernel:

Quote:

sycamorex@linux-tree:~$ lsmod | grep snd
snd_ice1712 57332 1
snd_ice17xx_ak4xxx 4000 1 snd_ice1712

snd_mixer_oss 15936 1 snd_pcm_oss
snd_pcm 72644 3 snd_ice1712,snd_ac97_codec,snd_pcm_oss

snd 49508 16 snd_ice1712,snd_ak4xxx_adda,snd_cs8427,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_i2c,snd_ mpu401_uart,snd_seq_oss,snd_seq,snd_timer,snd_rawmidi,snd_seq_device
soundcore 7520 1 snd

it seems that they are loaded, but as I mentioned before it doesn't work

2. The second method is by using the aoss script
$ aoss gtick
After starting up gtick this way, when I want the metronome to start 'ticking', only the first 'tick' is audible.
Then it keeps working but there's silence coming from gtick.

On the official gtick website they say that deb and rpm packages may be slightly out of date, so I removed gtick and tried to install it from source, however I got the following error:

Quote:

checking for strtol... yes
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for DEPS... configure: error: Package requirements (gtk+-2.0 gthread-2.0) were not met:

No package 'gtk+-2.0' found
No package 'gthread-2.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables DEPS_CFLAGS
and DEPS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I've got libgtk2.0-0
Also, when I tried to echo $PKG_CONFIG_PATH, it seems that it's empty.

Any suggestions will be appreciated

thanks

Try this

Code:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig

Good luck. ;-)

Thanks for your reply, however I googled the 2 missing packages and what turned out was that I needed:

1.libglib2.0-dev to get gthread package
2.libgtk2.0-dev

All the dependencies have been satisfied, and I managed to install it without problems.
But the problem with this version of gtick is exactly the same. I can't use gtick and any
other application using sound simultaneously

If I run gtick, I can't play any song ('device is busy' - I tried amarok, mplayer, xine, xmms). When I run any of those applications, in turn, I can't produce any sound from gtick.
thanks for any suggestions

I've googled up some references to the envy24control Mixer. That may give you more control over the card. You may also want to look into Dmix.
Good luck. ;-)
