ALSA: E-MU 0404 is not working

Hi,

I'm having problems with my soundcards. I have two soundcards of which the first one is integrated and it's working without any problems. The second one is E-MU 0404, which isn't working at all. It seems that my E-MU card isn't recognized at all, at least not by ALSA.

As far as I know, the card should be supported by ALSA and that's where I need some help. Is it possible to use both the cards or should I disable the integrated one to get my E-MU card working? I haven't done any additional configuration yet, the integrated sound card worked out of the box.

Here are some details about my system:

Re: ALSA: E-MU 0404 is not working

hi, have you unmuted the channels?

the wiki says:
amixer set Master 90% unmute
amixer set PCM 85% unmute

I had to use too (IIRC)
amixer set Front 90% unmute

bye!

Re: ALSA: E-MU 0404 is not working

Hi,

I'm afraid I cannot do any adjustments for my card before it's recognized. I think the problem is that I don't have right kernel modules loaded or ALSA needs some special configuration for two cards to get working. And that's the problem: I don't know exactly where the problem is

Cheers

Re: ALSA: E-MU 0404 is not working

Ok, I think I've traced the problem down to the point where it's out of my hands. Anyways, here's a description about the problem for documentation.

I checked dmesg for errors and I found this:

emu1010: EMU_HANA_ID=0x7f
emu1010: filename emu/emu0404.fw testing
firmware: emu/emu0404.fw not found. Err=-2
emu1010: Loading Firmware file emu/emu0404.fw failed

Which indicated that my card needs a firmware, so I downloaded and installed the firmware package from ALSA's website. After that the error changed to:

emu1010: EMU_HANA_ID=0x7f 
emu1010: filename emu/emu0404.fw testing 
emu1010: Loading Hana Firmware file failed, reg=0x7f

This seems to be a problem with ALSA driver/firmware and the first revision of E-MU 0404.[1][2]

Hopefully this gets fixed at some point.
