Subject: [gentoo-user] audio: can hear sound from line/mic but cannot record it

1 Hi,
2 I have an odd problem with audio recording.
3
4 When I plug my guitar to the line in/mic in, it plays. I can hear the
5 sound fine. So the input device seems to work correctly.
6
7 But when I try to *record*, no matter the application (audacity, rezound,
8 arecord) the application freezes and no output file is made. arecord
9 actually spits out a 44-byte header, and nothing else.
10
11 strace-ing the application clearly shows that the app just freezes.
12
13 Relevant things I changed after last time it worked correctly may be:
14 - the kernel (from 2.6.16 to 2.6.18-r6)
15 - alsa-lib (from 1.0.11 to 1.0.14)
16
17 alsa drivers are compiled in the kernel. I run x86, stable, gcc 4.1.1.
18
19 The audio card is: (lspci output): Multimedia audio controller: Silicon
20 Integrated Systems [SiS] AC'97 Sound Controller (rev a0)
21
22 I tried messing with alsamixer settings but with no avail. Relevant
23 kernel settings seem OK...:
