Report post Posted August 23, 2017 Problem solved. For Mainline, do this 1) alsamixer 2) press TAB (Make sure it falls to F4: CAPTURE) 3) Move to Mic1 (Use arrow keys) 4) Press SPACE and (L R Capture will appear) Quit and you are good to go. 1 Orfait reacted to this Share this post Link to post Share on other sites

Earlier I had arecord: pcm_read:2032: read error: Input/output error when I'm trying to record. After I did some modifications which you mentioned above, it worked! (gives no error and terminates after times up when I set a time duration). But when I'm trying to play that audio using aplay test2.wav I got an error saying that test2.wav: No such file or directory. But the file already exists. So how can I sort it out? Thanks!

So if you did a arecord with the filename ./test2.wav then you also should use the same filename for aplay e.g. aplay ./test2.wav or you could give a complete path to the arecord and aplay like /temp/test2.wav Share this post Link to post Share on other sites
