file is unwritable

[Anveshaaaa]

we want to change the card value, but keep getting the error that the file (sc_asound.conf) is unwritable. Does anyone know how to fix this?

Did you try editing as 'sudo'?

[Anveshaaaa]

yes thank you, we are able to change it now! :) But we have another issue, when we type 'arecord -l' we don't see a list of capture hardware devices and when we type 'aplay -l' we don't see loopback devices

I am having this same issue. I am also getting errors when trying to install numpy.
