Low recording quality on ice1712

Low recording quality on ice1712

[Lars Heineken]

Hi !

I've been a member of htis list some time ago, and now I'm facing a new 
problem: Playback through my Terratec EWX 24/96 (ice1712) on Mandrake 
9.1 is fine and crysrtal clear, but recorded stuff (using arecord -f cd) 
sounds damped, just like beeing recorded in 22000 kHz. I have created an 
.asoundrc in my home directory identically to the example on the alsa 
project page but it didn't help.
I tried to record in WinXP, and as always, recording works fine there no 
damped sound. It's definitely not a hardware issue.

I would like to be guided by someone with more experience than me, to 
find the reason for the poor ice1712 sound quality, I consider serious.

Regards,

Lars Heineken.

i suspect the mixer misconfiguration, rather than a general problem of
the ice1712 driver.  note that ~/.asoundrc has nothing to do with the
mixer setting.

how did you adjust the mixer setting?

I just figured out that Mandrake used a very old alsa version (0.9rc8)
and I decided to switch to the latest. It's working fine now.
I'm still investigating wether this is related to my driver upgrade or
the fact that I freed up another IRQ. Could a shared interrupt produce
damped sound while recording ? (The sound was not digitally distorted at
any time)

Regards,

Lars.
