[Alsa-user] PS3 Eye Microphone issues..help pls

[Mihai T. <mi...@du...>]

Hello all,


I was wondering if you could lend me a hand or offer some suggestion on 
a strange matter I'm confronting with.

I have taken a PS3 Eye Webcam from my PS3 and placed it into my USB port 
on the home computer.

So far so good, I also compiled the video driver made for it but this is 
not the subject of this problem.

Whenever I try running for example alsactl store I get:

# alsactl store
alsactl: get_control:262: Cannot read control '2,0,0,Mic Capture 
Volume,0': Invalid argument

the webcam is seen as:

cat /proc/asound/cards
 0 [Audigy         ]: Audigy - Audigy 1 [SB0090]
                      Audigy 1 [SB0090] (rev.3, serial:0x531102) at 
0xb880, irq 23

also:

#dpkg -l | grep alsa
ii  alsa-base                                  
1.0.17.dfsg-2ubuntu1                    ALSA driver configuration files
ii  alsa-utils                                 1.0.17-0ubuntu3         
ii  gstreamer0.10-alsa                         
0.10.21-3ubuntu0.1                      GStreamer plugin for ALSA

Running system is an Ubuntu 8.10, kernel 2.6.27-14-server.


I did some digging and asked around and on the ps3 driver forum (the one 
for the video) the guys stated that the microphone worked very well by 
default without their intervention or any special driver adding.
So I guess alsa picked it up and it was ok from the start. What I don't 
know is what kernel version they were using and what alsa version, what 
compile flags, etc.


Can you help me solve this issue if anyone ever ran into something similar ?
I'm really stuck with it and no idea what to do next.


Thanks,
Mihai
