https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251125 --- Comment #23 from Florian Walpen <dev@submerge.ch> --- Quick status update from my side: I have some working code for the 24bit case, we can actually use the conver= sion functions from jack2 with different parameters - i was misled by a comment = in the sources. The produced format will be native endian (AFMT_S24_NE) like in the 16bit and 32bit cases. That alone still resulted in choppy, slowed down audio. I had to set the fr= ames per period (parameter "period") manually to 1365, which is the number of fr= ames written in one block: 8190 blocksize / 2 channels / 3 bytes sample size. Gi= ven this setting audio output was clean. I thought that this value would propag= ate automatically through JackAudioDriver::SetBufferSize(), but it's somehow not respected. So patches are not quite ready yet. The other problem i have is with detection of input channels, my 2-channel = USB interface is always detected as mono: > JackOSSDriver::OpenInput driver forced the number of capture channels 1 I tried to use SOUND_PCM_READ_CHANNELS, same as above, any ideas? --=20 You are receiving this mail because: You are the assignee for the bug.=
