Hi, Have been trying to
get ALSA working without success. Have had a look at the code in aplay
and it appears as though none of the devices in /dev/snd/ are able to be
opened. When attempting to run the alsa-utils I get the following output
as shown below. Included the dummy device in this instance of the kernel
configuration to test if the card specific to the actual sound hardware was the
problem (as you can see its a problem with the dummy device as well).
Would appreciate any assistance or information that may be of help to me.
Have tried to include as much information as possible- see below. cheers, Geoff Crowther Output from ./aplay
