Thanks for your reply. This isn't really suitable yet to replace FFADO . It provides this as separate devices so I cannot access all channels at the same time in jack as in FFADO. Although I don't typically use the ADAT ports other might, however I am always using a combination of channels 1-16 and channels 17 & 18 combined, sometimes all of them. The device is a hardware mixing desk and all ports are designed to be used simultaneously.. Latency performance is also much worse. FFADO will allow a buffer size of 64, ALSA will not start below 256. I prefer to work at 128 or lower. Here is the output you requested. root@kxdaw:/home/allan/Downloads# cat /proc/asound/card1/dice sections: global: offset 10, size 95 tx: offset 105, size 142 rx: offset 247, size 282 ext_sync: offset 529, size 4 unused2: offset 0, size 0 global: owner: ffc1:000100000000 notification: 00000040 nick name: ZED R16 clock select: internal 44100 enable: 1 status: locked 44100 ext status: 000000c0 sample rate: 44100 version: 1.0.11.0 clock caps: 44100 48000 88200 96000 adat internal clock source names: AES12\AES34\AES56\AES78\AES_ANY\ADAT\ADAT_AUX\Word Clock\Unused\Unused\Unused\Unused\Internal\\ tx 0: iso channel: 0 audio channels: 16 midi ports: 1 speed: S400 names: CH1/CH1/2\CH2/CH1/2\CH3/CH3/4\CH4/CH3/4\CH5/CH5/6\CH6/CH5/6\CH7/CH7/8\CH8/CH7/8\CH9/CH9/10\CH10/CH9/10\CH11/CH11/12\CH12/CH11/12\CH13/CH13/14\CH14/CH13/14\CH15/CH15/16\CH16/CH15/16\\ ac3 caps: 00000000 ac3 enable: 00000000 tx 1: iso channel: 1 audio channels: 10 midi ports: 0 speed: S400 names: L/MAIN L/R\R/MAIN L/R\ADAT1/ADAT1/2\ADAT2/ADAT1/2\ADAT3/ADAT3/4\ADAT4/ADAT3/4\ADAT5/ADAT5/6\ADAT6/ADAT5/6\ADAT7/ADAT7/8\ADAT8/ADAT7/8\\ ac3 caps: 00000000 ac3 enable: 00000000 rx 0: iso channel: 2 sequence start: 0 audio channels: 16 midi ports: 0 names: CH1/CH1/2\CH2/CH1/2\CH3/CH3/4\CH4/CH3/4\CH5/CH5/6\CH6/CH5/6\CH7/CH7/8\CH8/CH7/8\CH9/CH9/10\CH10/CH9/10\CH11/CH11/12\CH12/CH11/12\CH13/CH13/14\CH14/CH13/14\CH15/CH15/16\CH16/CH15/16\\ ac3 caps: 00000000 ac3 enable: 00000000 rx 1: iso channel: 3 sequence start: 0 audio channels: 10 midi ports: 0 names: L/MAIN L/R\R/MAIN L/R\ADAT1/ADAT1/2\ADAT2/ADAT1/2\ADAT3/ADAT3/4\ADAT4/ADAT3/4\ADAT5/ADAT5/6\ADAT6/ADAT5/6\ADAT7/ADAT7/8\ADAT8/ADAT7/8\\ ac3 caps: 00000000 ac3 enable: 00000000 ext status: clock source: internal locked: 1 rate: 44100 adat user data: - On Thu, Apr 21, 2016 at 1:21 AM Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx> wrote: > Hi, > > On Apr 20 2016 23:31, Allan Klinbail wrote: > > Using kernel 4.4.0 from Ubuntu > > > > The ALSA driver limited the device to only 16 inputs and outputs, however > > it has a total capability of 26 > > This is comprises of 16 inputs and outputs on the desk channels, a stereo > > main pair of outputs and inputs for the master bus > > 8 additional ins and outs to support the ADAT ports on the back > (availoable > > in 44.1 and 48 khz modes, but not 88.2 or 96 Khz > > This is fixed in Linux kernel 4.6. > http://mailman.alsa-project.org/pipermail/alsa-devel/2016-March/105462.html > > The backported codes are available in my private repository.
