[PlanetCCRMA] Re: Echo Mona Laptop driver

[Juan Reyes]

Looks like you already have a card using ALSA (i.e. card 0). It might be
the laptop internal card. There are instructions on planetCCRMA for
using multiple soundcards on /etc/modules.conf. You can check which card
with ' cat /proc/asound/cards '. 

As far as '/var/log/messages' looks like PCMCIA is doing its job and if
I am not mistaken the card is seen as PCI. Furthermore when you do
'lspci ' the card is on the PCI list. So the ALSA module might try
looking for the PCI card.

But you might be right there can be a problem with the driver. On the
ALSA matrix they say is not on the CVS. It might be that the chipset is
too new. If you are able to get the latest version of the snd-mona
module and nn order to compile the ALSA drivers you will need the
planetccrma kernel-sources for the kernel you are using.

Perhaps at this point it would be a good idea to contact the snd-mona
author with your setup (serial number and chipset) to see what is the
status of the driver.  You  need to contact: pochini@shiny.it , don't
write to the manufacturer since they probably don't even know what ALSA
is all about.

Good luck and keep us posted,
