No microphone input with alsa 1.0.20 with an CMI9761A+ chip on-board
My alsaconf says 'No supported PnP or PCI card found' and alsamixer lists
Card: SiS SI7012
Chip: C-Media Electronics CMI9761A+
I set my microphone to 81 volume, with mic boost and with Mic Selection set to Mic1, but I get no input from my microphone with arecord nor skype. I tried the headset on a laptop and it works correctly, so I guess this is a driver or ALSA configuration problem
I have kernel 18.104.22.168, with ALSA and SiS on-board sound drivers built-in.
lspci | grep audio says:
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] AC'97 Sound Controller (rev a0)
I compiled and installed alsa-lib 1.0.20 and alsa-utils 1.0.20, with no change. Compiling alsa-drivers resulted in a message 'You have built-in ALSA in your kernel'
I have KDE on Slackware and KMix also shows microphone level set to around 81, with Mic1 selected as the current mic. When Skype is getting microphone input, KMix shows both Mic and IEC958 Playback AC97-SPSA devices as a record source (the red record led lights up). Is this ok or should it only use Mic device as the record source ?
My speakers and headset can be heard correctly, but I get no microphone input. Do you know what can I do ?
