[PlanetCCRMA] cinelerra on athlon/duron

[Luc Tanguay]

Still having same problem.

More info on my setup.

The audio samples have been recorded at 44100 Hz.  They contain one 
channel only (mono).

Settings | Preferences | Playback:
- Samples to read ... -> 131072 (=128*1024)
- Sample to send ... -> 2048
- Use software for positioning -> checked
- Audio driver -> OSS (why ALSA is not listed?)
- device path -> /dev/dsp
- bits -> 16 bit linear
- channels -> 2

Here's the output of 'soundtest' from CCRMA distribution of Cinelerra:

*** Half duplex
Couldn't enable full duplex audio.
          fragments fragstotal fragsize   bytes  TOTAL BYTES AVAILABLE
Playback:         2          2    32768   65536        65536
Record:           0          2    32768       0        65536

Why does it say 'half duplex' ?


I've also tried the ' LD_ASSUME_KERNEL=2.2.5 cinelerra' trick and it 
does not help.

Regards,
Luc
