Hello All, I am new to this list.. I am facing a problem. Here it is. I am using Intel i8x0 sound card under FEDORA CORE3. While in Windows I can run Media Player and Other Media Applications Simultaneously but under FEDORA CORE supposing I try to run a media player while the other is running then it gives me a message box displaying that "Please verify that your sound card is configured properly And no other application is using the sound card" I am using the ALSA driver for the Intel i8x0 card. I want to know how can I use the same card for the simultaneous multiple multimedia applications running on the same machine under Linux. Thanks, Ashutosh. |

Put pcm.!default { type plug slave.pcm "dmix" } in your /etc/asound.conf |

This is already enabled by default for Intel AC'97 controllers in recent ALSA versions. I guess the OP uses programs that still use the old OSS API. Regards, Clemens |

THanks, I am using FEDORA CORE 1 and on the other machine FEDORA CORE 3 Well I didn't find any asound.conf but found asound.state where the states were listed. I added the below mentioned lines there, but no effect. In turn now my audio reception channel is getting problem. It is not getting open. Please help.

Hi, I did that also. But no change. I tried simultaneously playing a wav file from XMMS and Real Player. But the same problem. =20 I am not getting anything. I created .asoundrc file also.

OK. But other applications like Gnomemeeting and Audio Player use the same..

Hello, I don't know whether you received my previous mail, but I am not able to= =20 do that also. I built the latest ALSA drivers and followd the process that is given on= =20 the ALSA site, but no improvements. And also I am not getting how to turn= =20 off the artsd in FEDORA CORE 3. Since I was not having the /etc/modules.conf so I made the changes in the= =20 /etc/modprobe.conf. But nothing happened. Instead when I tried to do the modprobe snd-intel8x0= =20 then it gave me the error related to the No Symbol Found etc. Please help. THanks, Ashutosh.

I have mplayer compiled to use the ALSA API by default. I haven't tried it with OSS, but I'm guessing it wouldn't work considering what was said earlier in the thread. It's probable/likely that playing audio from the applications you're using, simultaneously, won't work due to the OSS API that they are using. Perhaps newer versions use ALSA and those will work. -Andy |

Thanks, But I didn't find any asound.conf or .asoundrc file. So I created that. I= =20 installed the latest ALSA driver. And my application that is Real Player an= d=20 Audio Player (XMMS) use ALSA plugin rather than OSS. I also checked with the GnomeMeeting which uses ALSA plugin. But in vain.
