[alsa-devel] Using speaker-test for sound cards which dont support mmap
by Pharaoh . 12 Jul '07

Is it possible to use speaker-test for sound cards which do not support mmap? I straced speaker-test and it uses mmap call, can we bypass this?

[alsa-devel] Help with ALSA application development
by Paul Kavan 12 Jul '07

12 Jul '07

Hello: I am still trying to write my own basic application that captures and plays audio. I am working in an embedded linux environment and have the drivers working well. I can use arecord/aplay without any problem. However, I have been trying to follow some web examples for simple capture and playback without any success. Does anyone know of some sample code for S8 formatted, 8k rate capture and playback. I think my problem is two-fold. First is getting the hw-params set correctly. I have a function call that sets the interface up. I am trying to use the same params that aplay -v returns to me, but perhaps I have them wrong somehow. Secondly is buffering the samples. I am not sure I have that correct. Does anyone have some pointers on that? I have attached my code. If anyone has some time and insight into this, I would greatly appreciate it. Thanks. Paul

[alsa-devel] non-interleaved mode
by Steve Longerbeam 11 Jul '07

11 Jul '07

Hi, The driver for the sound engine I'm working on requires NONINTERLEAVED. Will ALSA core give my driver a full period of left-only samples, followed by a full period of right-only samples? Or are left/right samples split within a single period (ie. first half of period is left samples, second half is right samples)? Thanks, Steve

[alsa-devel] Query regarding sampling rates etc
by Pharaoh . 11 Jul '07

11 Jul '07

Hi, This is a very vague question, just thought of asking it after hours of debugging. I am testing my alsa driver, written for omap 730/850 based board. I am testing it by using aplay. Despite checking clocks, sampling rates etc many times and after doing many combinations thereof, I cant hear anything more than a noise which changes and becomes more like the original .wav file as I change various params like sampling rates/clocks etc. It becomes close to the actual thing, but not better. Any idea what are the params I should be tweaking? I know this is h/w dependent. -pharaoh

[alsa-devel] Alsa lib configure asoundlib.h
by Fausto Carvalho Marques SIlva 11 Jul '07

11 Jul '07

In salsa library(this library really saved my life, from am alsa-lib of 600K to 45K!!!), developed by Takashi Iwai, the creation of asoundlib.h is dynamic and based on the configure options ( --disable-mixer will remove mixer.h from asoundlib.h). Can alsa-lib do the same??I think it is a good "cleanup" way of doing client header files. Example from configure.ac from salsa-0.0.6: " echo "Creating asoundlib.h..." cp "$srcdir"/src/asoundlib-head.h src/asoundlib.h test "$mixer" = "yes" && echo "#include \"mixer.h\"" >> src/asoundlib.h test "$rawmidi" = "yes" && echo "#include \"rawmidi.h\"" >> src/asoundlib.h test "$hwdep" = "yes" && echo "#include \"hwdep.h\"" >> src/asoundlib.h test "$timer" = "yes" && echo "#include \"timer.h\"" >> src/asoundlib.h test "$sndconf" = "yes" && echo "#include \"conf.h\"" >> src/asoundlib.h test "$sndseq" = "yes" && echo "#include \"seq_event.h\"" >> src/asoundlib.h test "$sndseq" = "yes" && echo "#include \"seq.h\"" >> src/asoundlib.h test "$sndseq" = "yes" && echo "#include \"seqmid.h\"" >> src/asoundlib.h cat "$srcdir"/src/asoundlib-tail.h >> src/asoundlib.h " Fausto Carvalho Marques Silva
