We have cross compiled PJSIP for android.We are using ALSA for sound and for this enabled the flag for Alsa in config_site.h. While cross compiling pjsip for android it looks for libasound.so library.So we cross compiled *alsa-lib* and *alsa-utils* and placed the libasound.so and alsa.conf file at android /data directory. But when we run the pjsua binary on *adb shell*,we get following errors: *snd_config_search_definition() : error = No such file or directorysnd_config_search_definition() : key = defaults.pcm.devicesnd_config_search_definition() : key = refersnd_config_search_definition() : error = No such file or directorysnd_config_search_definition() : key = defaults.pcm.subdevicesnd_config_search_definition() : key = refersnd_config_search_definition() : error = No such file or directorysnd_config_search_definition() : key = defaults.namehint.extendedsnd_config_search_definition() : key = plugsnd_config_search_definition() : key = plugsnd_config_search_definition() : key = shmsnd_config_search_definition() : key = shmsnd_config_search_definition() : key = teesnd_config_search_definition() : key = teesnd_config_search_definition() : key = filesnd_config_search_definition() : key = filesnd_config_search_definition() : key = nullsnd_config_search_definition() : key = null06:41:09.221 alsa_dev.c ..ALSA driver found 0 devices06:41:09.221 alsa_dev.c ..ALSA initialized* We get the same kind of errors when we try running *aplay -l* (cross compiled alsa-utils) on adb shell. Can we use ALSA in such a way for android? Is there any other way to access sound devices?
