No 2 programs can play sound at the same time?
 

Hi there,

Sometimes I watch movies, listen musics/radio, and tts (text-to-speech) books at the same time.

But I found whichever program I start making sound, no other programs can make a sound anymore.

Did I miss some setting?

:eek:

Congratulations! You just won the gold medal in the olympics for multitaskers.

Jokes aside, sorry, can't help you. A Slackware guru will most likely pop in soon and help you out.

That's why I always got a bad grade in school... :banghead:
But I just can't help myself from doing this...

If your profile's distribution is Slackware 14.1, I think that you use ALSA. Can you please post /etc/asound.conf? If there are no such file show "cat /proc/asound/modules" and output of "aplay -L".

P.S. Maybe the solution will be to create or edit /etc/asound.conf with something like
But I can't be sure until you post output of previous commands and files.

If recently nothing happened ALSA will always only give control over the sound device to one program. It just by design.

You could try pulseaudio. This is a wrapper over alsa. It takes control over the sound card and other programs give their output to pulseaudio.

You aren't right. The fact that ALSA plays sound from only one program by default doesn't mean that you can't configure it to work with two or more programs at the same time at all. And there is, of course, no matter to switch to PulseAudio only because of it.

Always thought it was ALSA that gave only one prog the reign. But it was with OSS. Learned something new.

Two links I read up on.

It is ok if only one program can make sound at a time.
Thanks guys.

Hey, I have alsa and I have no problem playing movies on vlc and watching video in firefox or playing music with amarok at the same time. From what I have read somewhere, alsa takes the sound from each source and mixes them.

In fact, I once tried pulseaudio and I had that one sound per program issue. Whenever I would open vlc, any other program already playing would lose access to speakers. But with alsa it works fine.

I might be wrong, but maybe it has something to do with gstreamer and the gst plugins. I noticed that without the plugins there are less support for programs like amarok.

You could try to install the gstreamers and the gst plugins (good, bad, ugly). Just check which ones already come with Slackware.

It is strange. For example, if I am playing youtube in firefox, anything else can't make a sound. The same thing happens to others situations too.

It isn't strange. We have told you that ALSA can successfully works with more than one program at the same time. Please, read previous messages if you want to fix your problem and post output of console commands that I asked for.

Oh...I am sorry. I wasn't paying attention here.

Here you go:


And I already have a asound.conf:

Ok, so I suggest to edit /etc/asound.conf to the
I think that may fix it. If it wouldn't fix problem than try to specify 0 or 29 instead of 1. And if after all of that there will be no result replace it with your original settings.
