Description Andrew McNabb 2011-11-14 00:31:42 UTC
As of Fedora 16, ALSA no longer provides an option to select the input source for capturing. The sound card has two microphone channels: Mic (the microphone port) and Internal Mic (built-in microphone). If I run "alsamixer -c0", I see both microphone channels under playback. If I unmute the Internal Mic playback channel, I get feedback as expected. However, if I hit F4, I don't see the option to select an input source; the only capture channels are: Mic Boost, Capture, and Internal Mic Boost.

Details about the sound card from lspci -v are:

00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
	Subsystem: Samsung Electronics Co Ltd Device ca00
	Flags: bus master, fast devsel, latency 0, IRQ 43
	Memory at f0240000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
	Capabilities: [100] Virtual Channel
	Capabilities: [130] Root Complex Link
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd-hda-intel

Is there any other information I can provide? Did I report this to the correct Component in bugzilla? Thanks.

I should clarify that I could select between the input sources in Fedora 15.

By the way, when I manually selected the model 'samsung-nc10', the following was in dmesg, but alsamixer behaved exactly as described above.

[   14.509502] ALSA sound/pci/hda/hda_codec.c:3934 hda_codec: model 'samsung-nc10' is selected
[   14.541648] input: HDA Intel Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input7
[   14.542144] input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input8

I forgot to include the kernel version in my original report:

kernel-PAE-3.1.1-2.fc16.i686
