Hi all, I have the following problem when reading from /dev/dsp (oss-emulation): when recording, if the source has two channels but the destination (i.e. my program) only wants one channel, then the sound I record is drowned out in a loud pulsing sound. If the destination has two channels as well, then there is no problem. Now, in the situation of 2 channels -> 1 channel, the oss-emulation layer does "channel reduction". I had a look at the source code but it made my head hurt... Does anyone else have this problem? Or could someone with a harder head than mine explain how the channel reduction is supposed to work, so I can make sense of the spaghetti? Thanks for any help! Duncan Sands. PS: The sound is S16_LE. PPS: The sound read into the buffers is ok before the channel reduction. PPPS: Since this is kernel code, it uses integer arithmetic, rather than float arithmetic (which is supported in the code - presumably because the code is shared with the oss-lib or something like that). _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
