Hi Alsa list! I bought a Toshiba Ultrabook Z830. It has jacks for external headset (with the usual greenn and pink connectors). I have no problem with sound output. As for input, the internal microphone is recognised but makes for a horrible capture. The Mic boost automatically goes up and this results in a lot of fan sound (I think) being caught. I want to use an external microphone/headset. I can hear a feedbock from the headset's microphone onto the headset speaker, but no sound is captured. I can't switch the input source to the external microphone. There is no such control available. trabbi:~# amixer contents | grep name= numid=15,iface=MIXER,name='Master Playback Switch' numid=14,iface=MIXER,name='Master Playback Volume' numid=2,iface=MIXER,name='Headphone Playback Switch' numid=1,iface=MIXER,name='Headphone Playback Volume' numid=21,iface=MIXER,name='PCM Playback Volume' numid=9,iface=MIXER,name='Mic Boost Volume' numid=6,iface=MIXER,name='Mic Playback Switch' numid=5,iface=MIXER,name='Mic Playback Volume' numid=10,iface=MIXER,name='Capture Switch' numid=11,iface=MIXER,name='Capture Volume' numid=16,iface=MIXER,name='IEC958 Playback Con Mask' numid=17,iface=MIXER,name='IEC958 Playback Pro Mask' numid=18,iface=MIXER,name='IEC958 Playback Default' numid=19,iface=MIXER,name='IEC958 Playback Switch' numid=7,iface=MIXER,name='Auto-Mute Mode' numid=13,iface=MIXER,name='Beep Playback Switch' numid=12,iface=MIXER,name='Beep Playback Volume' numid=22,iface=MIXER,name='Digital Capture Volume' numid=8,iface=MIXER,name='Internal Mic Boost Volume' numid=4,iface=MIXER,name='Speaker Playback Switch' numid=3,iface=MIXER,name='Speaker Playback Volume' numid=20,iface=PCM,name='ELD',device=3 I spent about 40 hours looking for a solution. I have been trying to fiddle with /etc/modprobe.d/alsa-base.conf, and /etc/modprobe.d/alsa-base-blacklist.conf. Here is a bit of background trabbi:~# aptitude show alsa-base | grep Version Version: 1.0.23+dfsg-4 trabbi:~# aptitude show alsa-utils | grep Version Version: 1.0.25-1 trabbi:~# uname -a Linux trabbi 3.2.0-1-686-pae #1 SMP Fri Feb 17 06:27:21 UTC 2012 i686 GNU/Linux trabbi:~# lsmod | grep snd snd_hda_codec_hdmi 26319 1 snd_hda_codec_realtek 142101 1 snd_hda_intel 21856 4 snd_hda_codec 63448 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel snd_hwdep 12943 1 snd_hda_codec snd_pcm 53390 4 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec snd_seq 39487 0 snd_timer 22356 3 snd_pcm,snd_seq snd_seq_device 13016 1 snd_seq snd 42691 15 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_seq,snd_timer,snd_seq_device soundcore 12921 1 snd snd_page_alloc 12867 2 snd_hda_intel,snd_pcm Any ideas?
