[Alsa-user] Microphone + AudioOut to HDMI
Hello!
Please help. I can't get working microphone at HDMI output.
I have computer: ASRock 330 ION.
1. audio video translated to LCD TV via HDMI cable.
2. external microphone connected to Mic IN.
3. headphones connected to Line Out (analog).
Sound from MP3/Video players go through HDMI output (hw:0,3) without
any problems.
Voice from microphone I _can_ hear only at analog output (headphones) (hw:0,0).
Please help forward voice from microphone to HDMI.
I have played with `asym', but unsuccessfully.
I want simultaneously sounds from video player and microphone go to output HDMI.
There are two versions `.asoundrc', but no one are forward microphone to HDMI.
Version 1 `.asoundrc' (simplifed version)
pcm.!default {
type asym
playback.pcm {
