Description: If I play something with one player, I am unable to record something on the same device. The same thing ispossible with the other cards I have. ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- related to 0000521 Jack + Alsa not working in full duplex,... ====================================================================== ---------------------------------------------------------------------- croiset - 05-09-06 14:09 ---------------------------------------------------------------------- I do the same test with alsa driver 1.0.11. I am able to record if I am not playing at the same time. If I am playing I obtain the open error at the same place as before. ---------------------------------------------------------------------- croiset - 05-09-06 15:49 ---------------------------------------------------------------------- We put some logs in rme96.c for debugging the problem. We obtain this : The function snd_rme96_capture_hw_params returns -EBUSY when we open the analog capture device when the analog output device is already opened in play mode because : rme96->playback_periodsize = 2048 rme96->capture_frlog = 2 params_period_size(params)=2048 then the tsst in line 1052 (alsa 1.0.11) is valid and then returns -EBUSY If the analog output device is not opened, when we capture, the values are : rme96->playback_periodsize = 0 rme96->capture_frlog = 2 params_period_size(params)=2048 then the test is not valid and the device is working.
