Summary: simple PCM helper function
Description:
/cvs/alsa-lib/test/pcm_min
ALSA lib pcm.c:7127:(snd_pcm_set_params) Unable to set buffer time
(latency) 500000 for PLAYBACK: Invalid argument
Playback open error: Invalid argument
sound card is au8830, the au88x0 driver only accept period size in power
of 2.

Summary: simple PCM helper function
Description:
/cvs/alsa-lib/test/pcm_min
ALSA lib pcm.c:7127:(snd_pcm_set_params) Unable to set buffer time
(latency) 500000 for PLAYBACK: Invalid argument
Playback open error: Invalid argument
sound card is au8830, the au88x0 driver only accept period size in power
of 2.
======================================================================

Yes and no. It's combination pow2 and periods == integer issue. If the
buffer size is 24000 and period size is 2048, then 24000 / 2048 = 11.7188
which is not integer value and then configuration fails.
In this case depends on the parameter order. Or a better fix maybe to
describe that buffer_size must be N * period_size with pow2 restriction
(create a list with all combinations).
I've tried to add a workaround to snd_pcm_set_params() to CVS, but it does
not prevent other apps using the hw_params ALSA API directly to fail.

To be sure: I'm talking about SNDRV_PCM_HW_PARAM_PERIOD_BYTES restriction.
See pci/emu10k1/emupcm.c code how you can use the
snd_pcm_hw_constraint_list() for this parameter.

It seem that au88x0 is the only driver which use
snd_pcm_hw_constraint_pow2()
/* Force equal size periods */
if ((err =
snd_pcm_hw_constraint_integer(runtime,
SNDRV_PCM_HW_PARAM_PERIODS)) < 0)
return err;
/* Avoid PAGE_SIZE boundary to fall inside of a period. */

snd_pcm_hw_constraint_pow2(runtime, 0,

return err;
