[Alsa-devel] Testing Audio driver
Hi,
I am writing Alsa driver on 2.6 kernel for arm platform.
I want to test my driver with application.
I took one sample application tried to map the functions.
*** sample application *
This program opens an audio interface for playback, configures it for
stereo, 16 bit, 44.1kHz, interleaved conventional read/write access. Then
its delivers a chunk of random data to it, and exits. It represents about
the simplest possible use of the ALSA Audio API, and isn't meant to be a
real program.
#include stdio.h
#include stdlib.h
#include alsa/asoundlib.h
main (int argc, char *argv[])
{
int i;
int err;
short buf[128];
snd_pcm_t *playback_handle;
snd_pcm_hw_params_t *hw_params;
if ((err = snd_pcm_open (playback_handle, argv[1],
SND_PCM_STREAM_PLAYBACK, 0)) 0) {
fprintf (stderr, cannot open audio device %s (%s)\n,
argv[1],
snd_strerror (err));
exit (1);
}
if ((err = snd_pcm_hw_params_malloc (hw_params)) 0) {
fprintf (stderr, cannot allocate hardware parameter structure
(%s)\n,
snd_strerror (err));
exit (1);
}
if ((err = snd_pcm_hw_params_any (playback_handle, hw_params)) 0) {
fprintf (stderr, cannot initialize hardware parameter
structure (%s)\n,
snd_strerror (err));
exit (1);
}
if ((err = snd_pcm_hw_params_set_access (playback_handle, hw_params,
SND_PCM_ACCESS_RW_INTERLEAVED)) 0) {
fprintf (stderr, cannot set access type (%s)\n,
snd_strerror (err));
exit (1);
}
if ((err = snd_pcm_hw_params_set_format (playback_handle, hw_params,
SND_PCM_FORMAT_S16_LE)) 0) {
fprintf (stderr, cannot set sample format (%s)\n,
snd_strerror (err));
exit (1);
}
if ((err = snd_pcm_hw_params_set_rate_near (playback_handle, hw_params,
44100, 0)) 0) {
fprintf (stderr, cannot set sample rate (%s)\n,
snd_strerror (err));
exit (1);
}
if ((err = snd_pcm_hw_params_set_channels (playback_handle, hw_params,
2))
0) {
fprintf (stderr, cannot set channel count (%s)\n,
snd_strerror (err));
exit (1);
}
if ((err = snd_pcm_hw_params (playback_handle, hw_params)) 0) {
fprintf (stderr, cannot set parameters (%s)\n,
snd_strerror (err));
exit (1);
}
snd_pcm_hw_params_free (hw_params);
if ((err = snd_pcm_prepare (playback_handle)) 0) {
fprintf (stderr, cannot prepare audio interface for use
(%s)\n,
snd_strerror (err));
exit (1);
}
for (i = 0; i 10; ++i) {
if ((err = snd_pcm_writei (playback_handle, buf, 128)) != 128)
{
fprintf (stderr, write to audio interface failed
(%s)\n,
snd_strerror (err));
exit (1);
}
}
snd_pcm_close (playback_handle);
exit (0);
}
**END***
**
I tried to trace back the application how i can map my driver routines with
the calls in application.
While tracing I couln't find the definition of of few functions like
snd_pcm_sw_params_set_start_threshold()
snd_pcm_hw_params_set_rate_near()
snd_pcm_hw_params()
snd_pcm_hw_params_free()
For few I could only find the prototypes.
My doubts are,
where can I find the definitions for these functions or Alsa APIs ?
Do i need to have any lib (alsa_lib) ?
If not how my driver can be accessed from application layer, I mean how
calls are mapped ?
Can anybody please help me in this regard.
Thanks

[Alsa-devel] OSS API redirector
Hi all, I would like to point all developers to the OSS API redirector which is in our alsa-oss package. It's universal piece of code which can redirect all OSS API calls (actually mixer PCM API only) to any shared library. Pros: - no more LD_PRELOAD hacks - any library can be used directly as endpoint - when used more applications will work (also some which does not work with LD_PRELOAD hack) Drawbacks: - still no fopen/fclose/fwrite/fread solution - applications must be a little bit modified Todo: - OSS sequencer API redirector (it shouldn't be too difficult) My original point is that we might persuade the binary only providers (mostly games vendors) to use this small piece of code, because there are no impacts regarding the application useability and the maintaince overhead of this code is minimal. The second goal is to use this redirector for all OSS applications in Linux distributions to make the routing over ALSA library more easy. Usage of this redirector for OSS API emulation in ALSA: export OSS_REDIRECTOR=libalsatoss.so And define appropriate pcm.dsp0 and pcm.mixer0 in ~/.asoundrc.

[Alsa-devel] Am I on the right way?
Hi all. I'm new to Alsa and its concepts, so I'd like to ask if the following assumptions are correct. A short explanation on the background: I'm currently examining different Voice over IP softphones on Linux. Every program that I've seen so far has the same limitation: it works with OSS. I guess you all know the drawbacks: I have to decide whether I want to have the softphone running, so that I can be called, or if I want to listen to some MP3s without being reachable by VoIP. Yes, I know of libaoss, but this causes some new problems. As we have a very flexible sound system available for Linux, it would be nice if there also was a softphone that makes use of this. Here is my idea: One of the tasks the softphone has is to record the voice of the local caller and encode with one of several standard codecs (such as G.711, GSM or whatever). The sofphone implementations I've seen always handle that codec-stuff by themselves. If I understood the concept of Alsa correctly, it should be possible to implement the different codecs as PCM plugins and route the sound through them: Soundcard -- PCM-Plugin-Codec -- Softphone By defining several routes, usage of different codecs would be simple, as long as it exists in the form of a PCM plugin. Benefit: handling of sound stuff is delegated to a part of the system that already has everything it needs to care about this task: Alsa. The softphone itself just needs to know which path is handling which Codec, and just has to read/write from/to that path. Are these assumptions correct? If so, do you have any pointers for me where I can learn more about the implementation of such PCM plugins? As you most likely can see, I'm unaware of the correct terms in the Alsa context (for example, I'm sure that you don't actually talk of paths for what I've described above). Please bear with me, I'm new to this stuff :) I'd like to hear your oppinion about this idea. Would it be possible to do? Is it a good idea to go this path?

[Alsa-devel] Clicks in output using intel8x0 driver (and a few questions)
I have a laptop with the following hardware: P4 3.06Ghz CPU 82801DB AC'97 Audio Controller 82801DB AC'97 Modem Controller nVidia GeForce Go5200 and software: Linux Kernel 2.6.3 (with some ACPI patches) Alsa 1.0.3 Glibc 2.3.2 For the most part the audio works fine, except when doing CPU intensive tasks. When there is a lot of CPU activity the audio will sometimes degrade into a lot of clicks and pops in the output, this can go on for some time and vary in loudness and rate of occurrence and sometimes it sounds like a whole audio fragment is skipped after which it will sometimes go back into sync again. I first noticed this in games, but afterward I noticed it when compiling the kernel or re-encoding a movie in the background but listening to music with XMMS (using OSS emulation). When audio gets bad with XMMS, it is sufficient to pause and play again, in which case it will be back to normal, and then degrade again eventually. While I'm at it, I'll throw a couple of questions out there (hopefully no one minds). I was curious what the state is of the intel8x0m driver, since I have an accursed CH4 82801DB AC'97 Modem Controller which is an HSF Conexant device. I have it working with the linuxant.com drivers, but they are rather unstable with the newer 2.6.4 kernel and contain binary code. Anyone have this working with this modem? My last question pertains to profiling. This laptop tends to have rather large latency stutters at regular intervals (probably between 1 and 2 seconds apart). This is noticeable particularly in games and when playing movies. I ran oprofile but the output isn't too helpful, since it would be nicer to know exactly when a section of code was taking a long time. Anyone know of some good strategies for tracking down latency issues with 2.6 kernels? Thanks in advance for any help :) Cheers!

Please take care that as reported in my post I used it on my old laptop (an ASUS M3410C/M3N, Intel Centrino), while I haven't tried yet on my new one (always an ASUS Intel Centrino, but now a M6842NWH/M6800N). I'll do my tests ASAP with the new 2.6.5-rc1 kernel which includes the 'intel8x0m'.
