Hi, Can anyone help point me to info on using ARM in embedded audio systems? Does anyone use a low-cost chip with I2S interface? Thanks Alan

And now it also breaks compilation of the following code (at least with glibc 2.5): #include <sys/select.h> #include <alsa/global.h> $ gcc -c --std=c99 x.c In file included from x.c:2: /usr/include/alsa/global.h:134: error: redefinition of 'struct timeval' /usr/include/alsa/global.h:139: error: redefinition of 'struct timespec' (Without #include <sys/select.h> only 'struct timespec' is redefined.) IMHO attempts to define structures which should be defined by system headers are too dangerous - if someone is using preprocessor flags which hide required parts of system headers, it is their problem, and the risk of mismatch is too high. BTW, <time.h> does not provide 'struct timeval' at all, even with _GNU_SOURCE - it defines only 'struct timespec'; however, this does not cause problems, because ALSA headers currently use only pointers to snd_timestamp_t, which works even without a complete definition of 'struct timeval'. We can try to include <sys/time.h> to get 'struct timeval', or even <sys/select.h> (which currently seems to provide both 'struct timeval' and 'struct timespec' even with -ansi, and http://www.opengroup.org/onlinepubs/009695399/basedefs/sys/select.h.html tells that it should always provide their definitions). > > > diff -r 7bc021fb4bf1027b23aa5429ceda1e1e35c7d126 -r 603411fd0c77712cab43cdd5afcf0ff4ebe51a7f include/global.h > --- a/include/global.h Fri Oct 06 10:38:39 2006 +0200 > +++ b/include/global.h Fri Oct 06 11:01:40 2006 +0200 > @@ -130,6 +130,18 @@ int snd_shm_area_destroy(struct snd_shm_ > > int snd_user_file(const char *file, char **result); > > +#ifndef _POSIC_C_SOURCE > +struct timeval { > + time_t tv_sec; /* seconds */ > + long tv_usec; /* microseconds */ > +}; > + > +struct timespec { > + time_t tv_sec; /* seconds */ > + long tv_nsec; /* nanoseconds */ > +}; > +#endif > + > /** Timestamp */ > typedef struct timeval snd_timestamp_t; > /** Hi-res timestamp */

Does this problem occur with S2D? What is the very first command that triggers this timeout error? I'm wondering what is the difference between them -- according to your report, reloading the module fixes the problem. But, the resume callback is almost identical with the re-initiailzation. Perhaps it's something to do with the power-state management. What about the patch below?

[alsa-devel] alsa-lib: pcm_softvol.c: attenuation curve - it seems to be too quiet at full volume
by John L. Utz III 25 Jun '07

25 Jun '07

Hello All; I am in release testing with a fix to our product to use 4 channels on a CMEDIA 8738-MC6 (previously we only used 2 channels on the CMEDIA and a separate soundcard for the 2 back channels). The 8738 is a pretty funny old duck of a chip and i am trying to work around a subset of it's many idiosyncracies. :-) The most glaring defect is the absence of hard volume on the back channels *and* that the back channel is louder than the front channel. Obviously, this is a great candidate for softvol! Softvol works quite well *except* that the max volume for the rear channel is now much quieter than it is without softvol. :-( Is there anything i can do to alter this behavior? I notice that there is an initial minimal DB in the file: #define PRESET_MIN_DB -51.0 is this where everything starts from? if i bump this up, will i get a higher max volume? tnx! johnu

[alsa-devel] Query regarding pointer callback
by Pharaoh . 25 Jun '07

25 Jun '07

Hi In Writing an ALSA driver, it is said that pointer callback is called usually from the buffer-update routine in the pcm middle layer, which is invoked when snd_pcm_period_elapsed() is called in the interrupt routine. Then the pcm middle layer updates the position and calculates the available space, and wakes up the sleeping poll threads, etc What are the other places from where pointer callback is called? If it is not called from any other routine then does it mean that interrupts are occuring?
