Hi,
trying to rewrite some oss code in alsa. Am having luck with
compiling and running arecord/aplay, but some of the other sample alsa
scripts (the API how-to) are giving me troubles like this :
pcm_params.c:2136: snd_pcm_hw_refine: Assertion `pcm && params' failed.
rtAudio (which might be good for my purposes) gave me this:
ALSA lib pcm_hw.c:791:(snd_pcm_hw_open) open /dev/snd/pcmC0D1p failed: No
such file or directory
+
essentially, I am trying to rewrite this old oss linux audio hook:
http://www.thesystemis.com/remark/linuxaudio2.c
any pointers or advice would be greatly appreciated. In particular, what
would be the ALSA equivalent of this:
ioctl(fd, SNDCTL_DSP_GETISPACE, &info);
return info.bytes;
Are there simple ALSA equivalents for the other ioctl calls?
thanks a ton!
best,
zach
