Hi I have a Fast Track Pro USB audio device which has stopped capturing sound using ALSA. When trying to capture, arecord claims the format S24_3BE is not supported: $ arecord -D hw:Pro,1 -f S24_3BE -c2 -r48000 -t wav test.wav Recording WAVE 'test.wav' : Signed 24 bit Big Endian in 3bytes, Rate 48000 Hz, Stereo arecord: begin_wave:2480: Wave doesn't support S24_3BE format... but: $ arecord --dump-hw-params -D hw:Pro,1 Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono HW Params of device "hw:Pro,1": -------------------- ACCESS: MMAP_INTERLEAVED RW_INTERLEAVED FORMAT: S24_3BE SUBFORMAT: STD SAMPLE_BITS: 24 FRAME_BITS: 48 CHANNELS: 2 RATE: [8000 48000] PERIOD_TIME: [1000 10922625] PERIOD_SIZE: [11 87381] PERIOD_BYTES: [66 524286] PERIODS: [2 1024] BUFFER_TIME: (458 21845250] BUFFER_SIZE: [22 174762] BUFFER_BYTES: [132 1048572] TICK_TIME: ALL -------------------- arecord: set_params:1233: Sample format non available Available formats: - S24_3BE According to http://alsa.opensrc.org/M-Audio_FastTrack_Pro, I have in /etc/modprobe.d/fast-track-pro.conf: options snd_usb_audio vid=0x763 pid=0x2012 device_setup=0x9 index=5 enable=1 to configure use of 24bit sampling rate. Attempting to capture sound through JACK also fails silently (literally: no error messages, just nothing arriving from system in JACK ports) but I'm sure it was working a few days ago. The only relevent thing to have changed since then is a kernel upgrade: linux (3.19.3-1 -> 3.19.3-3) System info is here: http://www.alsa-project.org/db/?f=257c31b8c899be7febffb0a34a8823e36aff2006 How can I get arecord working? (then I'll worry about recording in JACK but I suspect the issues are related) thanks, David. ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
