I have a 32-bit system running jessie that gives the following error the first time that I try to use ALSA following a reboot: ERROR: Cannot open audio device: hw:0,0 error number -16 Device or resource busy It doesn't seem to matter how long I wait following a reboot, the above error always occurs on the first use. If I run the same program again, even if I do so immediately, the error goes away and everything is fine. Is there some way to find out what process is using ALSA when snd_pcm_open() returns that error? (If indeed there is such a process.) Doc -- Web: http://www.sff.net/people/N7DR
