I'm having issues with an X-Fi Titanium and ALSA. The problem is that it appears to be impossible to capture without unmuting the channel I'm capturing from.
What do you mean exactly "unmuting the channel I'm capturing from"? If you mean to turn on/off "XXX Capture Switch", then it's a feature, no bug.
No, I mean that capture is possible only when mute=off and capture=on.
Which mute? Please be more specific.
The signal I'm trying to capture is coming in through the SPDIF-i channel, so I'm talking about the mute and capture flags on that channel. However, I also tried the analog input (line), and the problem is exactly the same on that channel.
Well, this is still unclear (what actually do you mean "channel") but let me guess:
the recording from either mic or line-in doesn't work unless you unmute via "Front Playback Switch" mixer element.
Correct?
Not really. I use gnome-alsamixer, and there is a mixer element called "SPDIF-i" that has a slider, a "Mute" switch, and a "Capture" switch. I connect a digital source to the SPDIF input on the card, and then I try to record it with arecord from device hw:0,0. The only way I'm able to record sound is by setting the Mute switch (of the SPDIF-i mixer element) to off and the Capture switch to on.
