Subject: How to read the sound card ?
Date: Sun, 30 Jul 2006 16:10:20 +0200 [thread overview]
Message-ID: <44CCBDCC.2010109@free.fr> (raw)
hello,
I want to read the data on the sound card (to do a fft and other
things). I have first tried the capture stream with snd_pcm_readi and
everything is working. My problem is that I want to read the sound
output (pcm or mixer). For example, I want to read the sound that xmms
or mplayer is writing on the sound card. If I just change
SND_PCM_STREAM_CAPTURE to SND_PCM_STREAM_PLAYBACK in snd_pcm_open,
snd_pcm_readi fails.
So my question is : how can I read the sound output with the alsa-lib ?
Thank you
