Hello,
I'm currently experiencing weird problems with my Terratec Aureon 7.1-Space
soundcard (snd-ice1724 driver).
1) Recording
When I try to use arecord for recording from analog inputs (for instance
'arecord -fS32_LE -r44100 -c2 -d1 foo.wav'), sometimes the pc crashes.
This behaviour depends on the samplerate I am trying to record with:
11025, 44100: crash - the screen goes blank after a few (approximately 2 or
3) seconds and the computer restarts
--------------------------------------------------------------------------------
22050: weird behaviour - one time arecord segfaulted, sometimes it just works
--------------------------------------------------------------------------------
88200, 176400: no crash, but the recording never completes (arecord reports
that it's writing to 'foo.wav' but this message keeps staying on the screen;
i aborted arecord after a few minutes and the system doesn't crash - it looks
as if arecord is waiting for data but isn't getting any)
--------------------------------------------------------------------------------
8k, 9600, 12k, 16k, 24k, 32k, 48k, 64k, 96k, 192k: works flawlessly
================================================================================
2) Analog Inputs
The 'Capture' control doesn't work as expected. When viewed in alsamixer this
control is shown as two lines of text which can either be "CD Left",
"CD Right", "Aux Left", "Aux Right", "Line Left", "Line Right", "Mic Left"
or "Mic Right".
If both lines show "CD Left" I can hear the Input from the internal CD
connectors, if "CD Right" is selected the internal AUX input can be heard,
"Aux Left" makes the input of the external Line connector available and
"Aux Right" is for the external microphone connector.
================================================================================
3) Digital Inputs
It seems to me as if the digital input isn't working - when I apply an
optical audio stream to the TOSLINK connector, I cannot record it with
'arecord -Dhw:0,1', it's also not possible to hear this signal if i set
the H/W controls to "IEC958 In".
================================================================================
4) Outputs
If I use xmms to play files to one of the surround outputs (hw:0,2,0 or
hw:0,2,1 or hw:0,2,2) or to the digital output (hw:0,1,0) and then switch
from X to one of the text consoles or move a window while using X, the sound
stutters (as if the content of a buffer was played repeatedly). What puzzles
me is that this problem doesn't appear if I use the analog front output
(hw:0,0,0).
Help would be greatly appreciated.
Regards,
Christoph Haderer
