Hello all 
Was just wondering if anyone else here has had this problem at all, namely trying to get any sort of audio recording working with audacity on the pandora. To date, I've not had a lot of luck!
First of all, I've been using this ( http://repo.openpandora.org/?page=detail&app=audacity ) version of audacity to try to record. I've also checked the mixer and under "capture" the circle (to capture from analog audio) is enabled, and so are the switches "Analog Left main mic" and "Analog Right main mic" in Switches.
In audacity I have it configured this way - Alsa, omap3pandora (hw:0,0) for output and omap3pandora (hw:0,1) for input. Channels are set to 1 (mono).
If I try to use these settings and then click on the record button in audacity, I get the following error;
"Error while opening sound device. Please check the input device settings and the project sample rate". (I tried changing the sample rate, but it did not make any difference).
In order to try to work around this problem I also tried a USB sound card. The device (as shown by lsusb on the pandora) displays as ;
"Bus 002 Device 003: ID 0d8c:0102 C-Media Electronics, Inc. CM106 Like Sound device".
The mixer also sees this device, calling it a "USB Sound Device (alsa mixer)". I tried to use audacity (as per the link above) with this sound card, but was once again met with failure. This time though I changed the input and output devices for audacity to "USB Sound Device: Audio (hw:1,0)". Unfortuntly this met with failure also, as audacity (when I tried to record with it) simply hung.
A little more investigation showed that alsamixer didn't see the USB sound card at all, only listing the internal sound in the pandora ("omap3pandora"). Worse still there were some nasty messages in lsusb;
[307.813659] aufs 3.2-20120109
[310.456909] asoc: interface omap-mcbsp-dai,1 hw params failed
[310.533081] cannot submit datapipe for urb 0, error -28 : not enough bandwidth
The "not enough bandwidth" error was repeated several times in dmesg.
So I'm having trouble in both areas - both with the pandora's internal sound and with an ordinary USB sound card too. x.x !
The alsa version I'm using on my pandora (according to cat /proc/asound/version) is 1.0.24 . The pandora is running kernel 3.2 on super zaxxon 1.54 . The pandora itself is an old first batch (256MB) version.
I know it appears I've combined or had two problems rather than one here but not sure what to do!
