Raspberry Pi Kernel and Firmware Versions?

Hi all:

Someone, and I won’t name names, but let’s call her Evil Rachel, was trying to solve a problem with rigctl and foolishly upgraded the kernel, kernel headers, and firmware on the Rpi 3 running her node. I think I fixed dahdi, but now I’m getting an error that chan_simpleusb cannot re-open the dsp device, and /dev/dsp does not exist. I’m hopeful downgrading, or some other solution you lovely folks may provide, will fix things. Or, is my best bet just to reimage the card?

Thanks, and 73,

Rachel AD9O

try:

as root:

dpkg-reconfigure asl-dahdi-linux-dkms

reboot

Should now be fixed. Check DAHDI is running by:

lsmod | grep dahdi

lsmod | grep dadhi shows

dahdi 237568 0

crc_ccitt 16384 1 dahdi

So I assume that’s fixed, but I’m still getting chan_simpleusb errors and not seeing /dev/dsp when I ls for it.

Rachel - OSS was deprecated about 10 years ago and removed (or marked broken) in recent kernels and as such things like /dev/dsp have been removed. Your only options are to emulate (my instructions below) /dev/dsp or go back to an old kernel that still has OSS built in.
