Hello, list! I have a few questions about the UCB 1300 audio driver for the 2.4.17-rmk5 kernel.
First, if I add machine-dependent code in ucb1x00-core.c to set the IRQ and GPIO pin, the warning message (Please remove machine dependencies...) appears. The interrupt is IRQ43. However, if I remove the code the interrupt is not detected (-1). If I ignore the warning message audio playback works as expected. Recording doesn't work and doesn't take any time (64k of data copied instantly). The dsp_info.c program I've picked from somewhere fails to SOUND_PCM_READ_BITS Further experiments indicate that the recording rate is very high, over 64000 samples/s - shouldn't be 8000 like the playback? Unfortunately my Via AC97 driver on the desktop doesn't work either so I cannot compare results to a working system :( Did someone successfully recorded audio using this driver?
