Hi list.

I' m using alsa-lib v1.0.14rc2 on gentoo-linux (v2.6.20-gentoo-r8) my soundcard is RME Hammerfall HDSP9632 (snd-hdsp driver) i have been using it for a while - all fine i only run a few applications for my sound experiments. one of those is Snd (from CCRMA), it was okay until i have done a few updates lately - kernel from 2.6.17 to 2.6.20 and alsa-lib as well. i'm not sure about either of these but i check Snd src-tree and the mailing list - nothing was changed ..

the error msg that i get is:

:(play) ;status of hw:0 hw_params status of hw:0 ACCESS: MMAP_NONINTERLEAVED RW_NONINTERLEAVED FORMAT: S32_LE SUBFORMAT: STD SAMPLE_BITS: 32 FRAME_BITS: [128 384] CHANNELS: [4 12] RATE: [32000 192000] PERIOD_TIME: (333 256000] PERIOD_SIZE: [64 8192] PERIOD_BYTES: [2560 393216] PERIODS: 2 BUFFER_TIME: (666 512000] BUFFER_SIZE: [128 16384] BUFFER_BYTES: [2560 786432] TICK_TIME: 1000 sw_params status of hw:0 start_mode: DATA xrun_mode: STOP tstamp_mode: NONE period_step: 0 sleep_min: 0 avail_min: 0 xfer_align: 0 silence_threshold: 0 silence_size: 0 boundary: 0 ;Invalid argument: hw:0: access type RW_INTERLEAVED not available can't play : Invalid argument: hw:0: access type RW_INTERLEAVED not available #f :

i had tried to modify audio.c in Snd's tree to use both ACCESS types given above , but it didn't help - showed device is busy error instead. i'm only studying C, so can't be sure ..

anyway here is a problem which i could not solve yet and haven't seen anyone helpful around #alsa, neither i could google anything out.

for a ref.: Cmdist mailing list Cmdist@ccrma.stanford.edu http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist and our discussion is here: http://ccrma-mail.stanford.edu/pipermail/cmdist/2007-July/004221.html

could anyone have a look at this at somepoint, please .
