With the 3.1.0 kernel, all microphone input (both with the internal microphone and any external microphone) is permanently muted, although sound output works OK. Microphone input works correctly with the 3.0 and earlier kernels. The only obvious difference between the 3.0 and 3.1 kernels is that with kernel 3.0.7, 'dmesg | grep HDA' gives this: HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 HDA Intel 0000:00:1b.0: setting latency timer to 64 input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input10 input: HDA Intel Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input11 input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input12 whereas with kernel 3.1.0 it just gives: input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input9 input: HDA Intel Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input10 input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input11 lspci -v gives the following audio hardware information: 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Subsystem: Lenovo Device 3be9 Flags: bus master, fast devsel, latency 0, IRQ 22 Memory at fc140000 (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 lsmod | egrep "snd|sound" gives: snd_seq_dummy 1023 0 snd_seq_oss 23792 0 snd_seq_midi_event 4408 1 snd_seq_oss snd_seq 39673 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 4121 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 33087 0 snd_mixer_oss 12647 1 snd_pcm_oss snd_hda_codec_realtek 205307 1 snd_hda_intel 18347 2 snd_hda_codec 64459 2 snd_hda_codec_realtek,snd_hda_intel snd_hwdep 4420 1 snd_hda_codec snd_pcm 57725 3 snd_pcm_oss,snd_hda_intel,snd_hda_codec snd_timer 14567 2 snd_seq,snd_pcm snd 40539 15 snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer soundcore 4129 1 snd snd_page_alloc 5445 2 snd_hda_intel,snd_pcm Chris
