I have an Asus XONAR U7 which only seems to allow 192k samples on the hw:U7,0 device sometimes. Using aplay --dump-hw-params, I saw different parameters with no clear idea of why they had changed. Most of the time 192k sampling works just fine, and --dump-hw-params gives the following. -------------------- ACCESS: MMAP_INTERLEAVED RW_INTERLEAVED FORMAT: S16_LE S24_3LE SUBFORMAT: STD SAMPLE_BITS: [16 24] FRAME_BITS: [32 192] CHANNELS: [2 8] RATE: [44100 192000] PERIOD_TIME: [125 2972155) PERIOD_SIZE: [6 131072] PERIOD_BYTES: [64 524288] PERIODS: [2 1024] BUFFER_TIME: (62 5944309) BUFFER_SIZE: [12 262144] BUFFER_BYTES: [64 1048576] TICK_TIME: ALL -------------------- But sometimes 192k does not work, but 48k works just fine, and the --dump-hw-params looks different. -------------------- ACCESS: MMAP_INTERLEAVED RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: [44100 48000] PERIOD_TIME: [1000 2972155) PERIOD_SIZE: [45 131072] PERIOD_BYTES: [180 524288] PERIODS: [2 1024] BUFFER_TIME: [1875 5944309) BUFFER_SIZE: [90 262144] BUFFER_BYTES: [360 1048576] TICK_TIME: ALL -------------------- Is there something that is changing the configuration of the sound card without my knowledge? Or is there a reason why 44100, 48000, and 192000 should not always be an allowable rate? ------------------------------------------------------------------------------ _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
