A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2076> ====================================================================== Reported By: jaime Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 2076 Category: PCI - cs46xx Reproducibility: always Severity: minor Priority: normal Status: new Distribution: Kernel Version: ====================================================================== Date Submitted: 04-26-2006 16:28 CEST Last Modified: 07-29-2006 15:35 CEST ====================================================================== Summary: arecord gives silence Description: IBM Thinkpad T21 with Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 01). alsamixer correctly mixes the inputs over to the line out (I can hear microphone in and line in successfully mixed) but arecord gives silence. I've tried using a usb soundcard on the same machine, and everything works fine there, so I think this is only the snd-cs46xx driver. I'm not sure what other info is useful - please let me know. Thank you. ====================================================================== ---------------------------------------------------------------------- Raymond - 06-29-06 09:32 ---------------------------------------------------------------------- Refer to https://bugtrack.alsa-project.org/alsa-bug/view.php?id=371#9010 Does it mean mean dsnoop is also not work with the hardware like CS46xx due to its design ? static struct snd_pcm_hardware snd_cs46xx_capture = { .info = (SNDRV_PCM_INFO_MMAP | SNDRV_PCM_INFO_INTERLEAVED | SNDRV_PCM_INFO_BLOCK_TRANSFER /*|*/ /*SNDRV_PCM_INFO_RESUME*/), .formats = SNDRV_PCM_FMTBIT_S16_LE, .rates = SNDRV_PCM_RATE_CONTINUOUS | SNDRV_PCM_RATE_8000_48000, .rate_min = 5500, .rate_max = 48000, .channels_min = 2, .channels_max = 2, ---------------------------------------------------------------------- Fred - 07-29-06 15:35 ---------------------------------------------------------------------- I've the same system, enabled sound recording via ADC Volume in alsactl and did the same test.
