Red Hat Bugzilla – Bug 121960
Cannot record from Creative Audigy 2 ZS Platinum Optical Input
Last modified: 2015-01-04 17:05:26 EST
Description of problem: I can play audio through the Optical Input on
my new Audigy 2 ZS Platinum, but I can't get Krec to record from that
input, and "Sound Recorder" crashes when I click the "Record" button.
Audio signal is coming from Roland VS-840EX digital multitrack
recorder. I can cat /dev/dsp to a file and when I cat it back to
/dev/dsp, I get a jumbled set of disordered but recognizable chunks of
what I tried to record, and it all seems to be recorded at about the
CD-quality sample rate and word-size. When I cat /dev/audio to a
file, then cat it back out, the result is "well-ordered" but telephone
quality, both for the optical digital in and the analog input on the
back of the card. I have seen nothing on http://www.alsa-project.org/
to suggest that there is a known problem with recording from the
Optical Digital Input on the Audigy.
Version-Release number of selected component (if applicable): Fedora
Core 2 Test 3
How reproducible: Behaves same way for me every time
Steps to Reproduce:
1. Install Audigy 2 ZS hardware
2. Install Fedora Core 2 Test 3
3. Connect optical cable
4. Attempt to record
Krec: "position indicator" moves, and it seems to think it's recording
something. No audio out on playback. I can play pre-recorded audio
files through Krec.
SoundRecorder crashes when I press the reocrd button, but plays
pre-recorded sounds perfectly
I should be able to record from the optical digital in, and get at
least CD quality.
is this any better with the current updates ?
I can now record with Sound Recorder and it doesn't crash, however I normally
record from optical with Glame (Glame has worked since the first set of kernel
updates after FC2-proper was released).
