Microphone records, but records nothing
Evening gents.
I'm running Debian x86 with no GUI on my netbook acting as a server. Sound works fine, MPD will play through the speakers. arecord also seems to work, but the recorded clip is silent The command Code:
arecord -d 10 /srv/samba/share/1TB/test2.wav The clip has no sound. Wat do? Cheers |
Run arecord and dump the output on screen. Is it all the same character you are seeing? (Usually an inverse video "?" or "}") Maybe only those 2 characters? Then you are recording zeros and you don't have sound being recorded. Use alsamixer to find out if your inputs are capturing.
If the output appears as garbage, really randon, redirect the output into a file using >. jlinkels |
I ran alsamixer, and int mic, ext mic and capture are all turned up
Here's the output alarazr@xorbi:/home$ arecord -d 10 /srv/samba/share/1TB/test.wav -v Recording WAVE '/srv/samba/share/1TB/test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono Plug PCM: Rate conversion PCM (48000, sformat=U8) Converter: linear-interpolation Protocol version: 10002 Its setup is: stream : CAPTURE access : RW_INTERLEAVED format : U8 subformat : STD channels : 1 rate : 8000 exact rate : 8000 (8000/1) msbits : 8 buffer_size : 1365 period_size : 170 period_time : 21333 tstamp_mode : NONE period_step : 1 avail_min : 170 period_event : 0 start_threshold : 1 stop_threshold : 1365 silence_threshold: 0 silence_size : 0 boundary : 178913280 Slave: Route conversion PCM (sformat=S32_LE) Transformation table: 0 <- 0 Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : U8 subformat : STD channels : 1 rate : 48000 exact rate : 48000 (48000/1) msbits : 8 buffer_size : 8192 period_size : 1024 period_time : 21333 tstamp_mode : NONE period_step : 1 avail_min : 1024 period_event : 0 start_threshold : 6 stop_threshold : 8192 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Slave: Soft volume PCM Control: Digital Capture Volume min_dB: -30 max_dB: 30 resolution: 121 Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 32 buffer_size : 8192 period_size : 1024 period_time : 21333 tstamp_mode : NONE period_step : 1 avail_min : 1024 period_event : 0 start_threshold : 6 stop_threshold : 8192 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Slave: Direct Snoop PCM Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 32 buffer_size : 8192 period_size : 1024 period_time : 21333 tstamp_mode : NONE period_step : 1 avail_min : 1024 period_event : 0 start_threshold : 6 stop_threshold : 8192 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Hardware PCM card 0 'HDA Intel' device 0 subdevice 0 Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : S32_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 32 buffer_size : 8192 period_size : 1024 period_time : 21333 tstamp_mode : ENABLE period_step : 1 avail_min : 1024 period_event : 0 start_threshold : 1 stop_threshold : 1073741824 silence_threshold: 0 silence_size : 0 boundary : 1073741824 appl_ptr : 0 hw_ptr : 16385 alarazr@xorbi:/home$ |

Bump, someone must have an idea what might be wrong with my mic configuration
