Hi all, I have some questions about the /default/ plugin. I am developping a softphone based on ALSA on Ubuntu 7.10. I use read/write IO. When I open a device with the /plughw /plugin, quite everything works fine, the quality sound is good. But with the /default/ plugin or the /dmix/ plugin ( the user can choose one of them ), I can't set my own hw parameters or sw parameters. Actually I set my own value of period size, buffer size, start threshold, stop threshold, but when I check in /proc/asound/cardx/pcm0p/sub0/sw_params or /proc/asound/cardx/pcm0p/sub0/hw_params, the values are totally different. For instance, the start threshold is set to 1 even if I set it to period_size. As a result, I get crackling sound. I suspect this is due to buffer underrun. Maybe if I could change the start threshold or the period size, the sound would be better. So my question: is it possible to modify this values for /default/ plugin without changing the alsa config file ( asoundrc ) ? Thank you very much Manu _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
