[alsa-devel] set_params:1073: not enough memory

Hello all,

I am trying to get alsa to work using buildroot to crosscompile to
i686-linux-uclibc. I am using the latest git version of alsa-lib and a
recent git version of alsa-util. I am stuck with the same error as in
the message included below when using aplay. So far I have been able
to narrow this down to the function set_params in aplay.c, lines 1070,

chunk_bytes = chunk_size * bits_per_frame / 8;
audiobuf = realloc(audiobuf, chunk_bytes);

chunk_size is 0 here and obviously the realloc fails.

Any ideas on what's going on here?

For the record, "aplay -L" lists the correct devices, "aplay -D null
test.wav" works ok and the card works correctly using alsa version
1.0.16 on standard suse 11.0.

Hello all,

I'm trying to get alsa 1.0.18 working on a ARM PXA processor and I'm
stuck with the following error message:

aplay /Sinus.raw -fcd
Playing raw data '/Sinus.raw' : Signed 16 bit Little Endian, Rate 44100
Hz, Stereo
aplay: set_params:1073: not enough memory

alsa kernel was compiled with alsa 1.0.16, alsa.conf, located in
/usr/share/alsa is the basic:

pcm.!default {
	type hw
	card 0

	ctl.!default {
	type hw
	card 0

also aplay -l and alsaconf store show the message:

ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0

However the card shows up /proc/asound/cards and alsamixer is able to
access it.

Any ideas?

Best regards
