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 16:34 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. ====================================================================== ---------------------------------------------------------------------- Fred - 07-29-06 15:35 ---------------------------------------------------------------------- I've the same system, enabled sound recording via ADC Volume in alsactl and did the same test.

This means that only one application can use capture device by changing default capture device from "dsnoop" to "hw" May be someone can rewrite the driver to use the hardware mixer to support multiple instances of capture like au88x0 http://hg-mirror.alsa-project.org/alsa-lib?f=8b52e1eece1b;file=src/conf/cards/CS46xx.conf;style=gitweb capture.pcm { type plug slave.pcm { @func concat strings [ "dsnoop:" $CARD ] - strings [ "hw:" $CARD ] } } Issue History Date Modified Username Field Change ====================================================================== 04-26-06 16:28 jaime New Issue 05-02-06 18:11 tiwai Note Added: 0009568 05-04-06 12:11 jaime Note Added: 0009613 05-08-06 12:14 atler Note Added: 0009645 05-24-06 14:03 fuman Issue Monitored: fuman 06-29-06 03:29 Raymond Note Added: 0010638 06-29-06 03:30 Raymond Note Edited: 0010638 06-29-06 09:08 atler Note Added: 0010642 06-29-06 09:27 Raymond Note Added: 0010643 06-29-06 09:32 Raymond Note Edited: 0010643 07-29-06 15:35 Fred Note Added: 0011306 07-29-06 15:36 Fred Issue Monitored: Fred 07-29-06 16:34 Raymond Note Added: 0011308 ====================================================================== ------------------------------------------------------------------------- Take Surveys.
