Subject: [gentoo-user] ALSA mixer as a capture device with Intel HDA cards
Date: Sat, 22 Dec 2012 23:58:36
1 Hello,
3 Today, I got a bit curious, and wanted to get some sound from a computer
4 which does not have any speakers at the moment. Mostly for fun, I
5 thought about using arecord and then listening to the file.
7 I decided to have a look around the mixer, with no luck. I remember
8 alsamixer showing an option to use the PCM mixer as a capture device,
9 but this was with other, older cards (possibly an ESS Maestro or a
10 Creative Enqsonic). Now, for this "Intel HDA" card, I don't see an
11 option to select the card's own output as the input stream.
13 From what I see, I'd simply assume this means the new card does not have
14 support for this in the hardware mixer, but I wonder whether I'm missing
15 something obvious. The card is listed, in lspci, as
17 Audio device: NVIDIA Corporation MCP72XE/MCP72P/MCP78U/MCP78S High
18 Definition Audio (rev a1)
20 And alsamixer lists it as
22 Card: HDA NVidia
23 Chip: Realtek ALC887
25 Any hints?
