Hello everybody. I'm trying to get Creative X-Fi Titanium PCIe to output 96000 audio through digital output (optical) and fail to do it.
System in question is Fedora 17 with kernel-3.4.6-2.fc17.x86_64 kernel and ALSA 1.0.25. Driver is snd-ctxfi 1.03, device is 05:00.0 Audio device: Creative Labs X-Fi Titanium series [EMU20k2] (rev 04) dmesg|grep -i alsa gives [ 4.172004] ALSA sound/pci/ctxfi/ctatc.c:1295 ctxfi: chip 20K2 model SB0880 (1102:0042) is found [ 4.490065] ALSA sound/pci/ctxfi/cttimer.c:424 ctxfi: Use xfi-native timer Anyhow problem is that even though X-Fi is supposed to work in HD modes, I can only can get it to work at 16/48k mode. It has few devices $ grep name /proc/asound/card0/pcm*p/info /proc/asound/card0/pcm0p/info:name: Front/WaveIn /proc/asound/card0/pcm0p/info:subname: subdevice #0 /proc/asound/card0/pcm1p/info:name: Surround /proc/asound/card0/pcm1p/info:subname: subdevice #0 /proc/asound/card0/pcm2p/info:name: Center/LFE /proc/asound/card0/pcm2p/info:subname: subdevice #0 /proc/asound/card0/pcm3p/info:name: Side /proc/asound/card0/pcm3p/info:subname: subdevice #0 /proc/asound/card0/pcm4p/info:name: IEC958 Non-audio /proc/asound/card0/pcm4p/info:subname: subdevice #0 Trying to playback through any device except for 0,4 produces silence on digital output (is that correct behaviour? On SBLive and Audigy analog devices were routed to digital out, but it doesn't seem to be the case here; am I missing something?). But 0,4 device seem to work only in two modes: 16/44.1 and 16/48. If trying to open it in 16/96 mode or 24/48, 24/96, 32/48, 32/96 modes it doesn't work - I get "invalid argument" and other similar errors from speaker-test or other applications. When using plughw device or outputting through pulse and such output locks to 16/48 mode, as seen in /proc/asound/card0/pcm4p/sub0/hw_params Some googling suggested that reference_rate module parameter controls it, but it can be set only to 48k and 44k, not 96k. I'm using default values, reference_rate=48000 and multiple=2. I tried changing rate and other values with iecset but it produces no effect. -- Vladimir ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
