A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2240> ====================================================================== Reported By: Alexis_Cousein Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 2240 Category: PCI - intel8x0 Reproducibility: always Severity: major Priority: normal Status: new Distribution: SuSE 10.1 Kernel Version: 2.6.16.13-4-smp ====================================================================== Date Submitted: 06-28-2006 18:21 CEST Last Modified: 06-29-2006 18:36 CEST ====================================================================== Summary: no microphone capture from motherboard onboard sound using intel8x0 driver Description: I'm using Skype on (ugh!) Windows for the moment, and microphone is fully functional. Plugged in the back of the PC (which should be Mic1); there's a second Mic input at the front. In SuSE 10.1, microphone doesn't work. krecord, arecord and Skype all record silence (or a constant pitch signal at very high gains), even though mixer settings appear correct. Evidently, some parts of ALSA do think they're recording from the microphone, because there is a 20dB boost to whatever constant pitch thinggummie is recorded when toggling the Mic boost in the mixer. Plugging Microphone in other port doesn't change anything; neither does selecting Mic2 in the mixer panel. lspci details: 00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02) yggdrasil:/proc/asound/card0/codec97#0 # cat ac97#0-0 0-0/0: C-Media Electronics CMI9780 PCI Subsys Vendor: 0x1462 PCI Subsys Device: 0x0480 Revision : 0x01 Compat.

06-29-06 17:36 ---------------------------------------------------------------------- Hm it's weird. Could you show the generated file via "alsactl -f file store" rather than amixer output? Also, for checking whether the recording works, try to change "Mix" as the capture source and run arecord during playing back something at the same time (e.g. aplay foo.wav on another terminal). It will record a loopback sound, i.e. you should be able to see the signaled being played in the recorded file. ---------------------------------------------------------------------- Alexis_Cousein - 06-29-06 18:36 ---------------------------------------------------------------------- Here's the aadebug output (the ALSA driver is now 1.0.12rc2, still no dice): ALSA Audio Debug v0.1.0 - Thu Jun 29 18:32:21 CEST 2006 http://alsa.opensrc.org/index.php?page=aadebug http://www.gnu.org/licenses/gpl.txt Kernel ---------------------------------------------------- Linux yggdrasil 2.6.16.13-4-smp #1 SMP Wed May 3 04:53:23 UTC 2006 i686 i686 i386 GNU/Linux Loaded Modules -------------------------------------------- snd_pcm_oss 42912 0 snd_mixer_oss 20736 1 snd_pcm_oss snd_seq 50640 0 snd_seq_device 11916 1 snd_seq snd_intel8x0 34332 0 snd_ac97_codec 87584 1 snd_intel8x0 snd_ac97_bus 6272 1 snd_ac97_codec snd_pcm 73092 3 snd_pcm_oss,snd_intel8x0,snd_ac97_codec snd_timer 24836 2 snd_seq,snd_pcm snd 53860 8 snd_pcm_oss,snd_mixer_oss,snd_seq,snd_seq_device,snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer snd_page_alloc 13576 2 snd_intel8x0,snd_pcm Proc Config ----------------------------------------------- CONFIG_SOUND=m CONFIG_SND=m CONFIG_SND_TIMER=m CONFIG_SND_PCM=m CONFIG_SND_HWDEP=m CONFIG_SND_RAWMIDI=m CONFIG_SND_SEQUENCER=m CONFIG_SND_SEQ_DUMMY=m CONFIG_SND_OSSEMUL=y CONFIG_SND_MIXER_OSS=m CONFIG_SND_PCM_OSS=m CONFIG_SND_PCM_OSS_PLUGINS=y CONFIG_SND_SEQUENCER_OSS=y CONFIG_SND_RTCTIMER=m CONFIG_SND_SEQ_RTCTIMER_DEFAULT=y CONFIG_SND_DYNAMIC_MINORS=y CONFIG_SND_SUPPORT_OLD_API=y CONFIG_SND_VERBOSE_PROCFS=y CONFIG_SND_VERBOSE_PRINTK=y CONFIG_SND_DEBUG=y #
