Hi, Sound subsystem has pcm_setstatus(device_t, char *) function, and its second param is string with size, limited to SND_STATUSLEN. Existing drivers puts something like "at io " followed by base address and size of device i/o and irq number. What exactly this status string should contain? Where it is used? Why have it? Since /dev/sndstat doesn't display this info, and mixer too.home | help
