Terratec EWS88MT

Terratec EWS88MT

[User for realtime audio]

Dear users,

I am using the ice1712-driver for my Terratec EWS88MT soundcard.

All compiles fine and the modules are loaded as well. After having 
compiled and installed everything
I tried to use the envy24control tool. After typing the instruction to 
start it nothing happens but the whole system is dead.
I have to reset by pushing the button.

The same happens when simply calling 'amixer contents'.

aplay ...wav does not play any sound even though all channels have been 
unmuted.

I have now added a soundblaster audigy as first soundcard which works well!

Has anyone experienced similar problems with that Terratec card?

Regards,
Hauke

which version are you using?
there was a dead-lock mutex bug in i2c code but should have been fixed
on the latest version.

please try the cvs version.

I am running kernels 2.4.16 with low latency patches and the RTC patch 
from alsa-package-rc3
and 2.4.18 without any patches alternatively. The alsa-package was rc-3 
and is now the current
CVS-version. In all cases envy24control and amixer contents lead to the 
system lock (amixer without contents works fine!)

I have started "strace envy24control" which let me know that

ioctl(4, 0xc245512, 0xbfffedb0)

is the instruction that causes the system lock. Multiple ioctls with 
only the third argument differing
returned 0 just before the system lock.

When calling amixer contents, the last message printed is:

numid=103, iface=mixer, name='Input Sensitivity Switch', index=1
    ; TYPE=enumerated, access=rw---, values=1, items=2
    ; Item #0 ='+4dBu'
    ; Item #1 = '-10dBV'


In comparison to the previous outputs coming from amixer contents
the following line is missing:
    ; values=0

Any idea?

Regards,
Hauke

thanks for spotting this!
there was actually a deadlock in this part.

fixed now on cvs.  please give a try.
(please note that on the cvs snd_ prefix is removed.)


ciao,

Takashi
