[alsa-devel] ALSA lib pcm.c:2175 snd_pcm_open_conf) symbol _snd_pcm_plug_open is not defined inside [builtin]
Hi, Iam using alsa lib version 1.0.22..and Iam running an alsa capture application. if Iam running this standalone application on my arm11 target ..it runs fine but when iam runnig this with my complete BD player integrated application it gives an error *ALSA lib pcm.c:2175 snd_pcm_open_conf) symbol _snd_pcm_plug_open is not defined inside [builtin] cannot open audio device plughw:0,0 (No such device or address).* ** I googled* *Which explained the errors meant I didn't have the Alsa plugins set via ALSA_PCM_PLUGINS in make.conf. I checked on target and x86 but there is no make.conf.
Please let me know what is the problem and what can I do to get rid of this problem...its bit urgent plz let me know as soon as possible.
--Thanks Asim

alsa-lib's configure script has the option --with-pcm-plugins=... to specify which plugins should be included. In your case, the plug plugin was obviously not included in this list.
(Many embedded application do need the automatic sample rate/format conversion and use the "hw" device.)
