Hi! It is not an issue anymore. I fixed the problem. But the problem was a little more complex.
It seems at that time some ALSA drivers lock the mixer or the audio input, but I didn't try enough to know what drivers exactly do this or what exactly is happening. I removed some drivers by hand, save the alsa configuration (using "alsactl store") then alsa began to work properly with pulseaudio. I don't know if it can happen now. To find this I have to play around with all the alsa drivers (what at this moment I don't have time to do). The script I did to remove the drivers that fixed the problem is this: ------------------------------- #!/bin/sh rmmod snd_cs4236 rmmod snd_hwdep rmmod snd_wavefront rmmod snd_cs4236 rmmod snd_hwdep rmmod snd_mpu401 rmmod snd_mpu401_uart rmmod snd_opl3_lib rmmod snd_wss_lib ------------------------------- What driver in particular cause the mixer or audio input/output to lock I have no idea. Perhaps the opl3_lib or wss_lib but I really don't know. Hope it help. Thanks for the atention and sorry for not posting this info before. Hugs!
