esoty usando arch linux y gnome 2.14.

ya agrege mi usuario a el grupo optical, donde tengo los "permisos" para grabar, pero al parecer es cosa del kernel, o es lo que lei en los mensajes...

alguna sugerencia?
saludos

Comprueba una vez más los permisos. Seguro que es eso. Puedes grabar como root?

Salu2

como root si puedo grabar, al menos lo deje asi, grabando ya es ganancia.

gracias de todas maneras

saludos
