Thanks for the tip. I will investigate. I must say that the ALSA configuration files look like pure voodoo magic to me. I found the following documentation: doc/asoundrc.txt http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html http://alsa.opensrc.org/.asoundrc http://alsa.opensrc.org/Dsnoop http://alsa.opensrc.org/AlsaTips Is there any other good documentation? How can alsa-lib open a device node several times when the driver only allows one process to open it? I see references to "ipc" in alsa.conf. My embedded kernel is compiled with # CONFIG_SYSVIPC is not set Does the dsnoop plugin require kernel support? -- Regards. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
