 |
|
Hey Gentooers 
I just configured my ALSA and sound seems to be working pretty well on Gentoo, but there's something weird in my microphone which is that after recording something and playing the sample audio, what I actually hear from it isn't my sound or anything, EDIT: Well, actually the recording is completely silent, the speaker DOES play other audios downloaded online etc...
Anyway, this is what I've been doing:
| Code: | localhost ~ # arecord --list-devices
**** List of CAPTURE Hardware Devices ****
card 1: Generic [HD-Audio Generic], device 0: Generic Analog [Generic Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
localhost ~ # arecord /tmp/text.wav
Warning: Some sources (like microphones) may produce inaudible results
with 8-bit sampling. Use '-f' to increase resolution
e.g. '-f S16_LE'
Recording WAVE '/tmp/text.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono
^CAborted by signal Interrupt...
arecord: pcm_read:2240: read error: Interrupted system call
localhost ~ # mpv /tmp/text.wav
[ffmpeg/demuxer] wav: Estimating duration from bitrate, this may be inaccurate
(+) Audio --aid=1 (pcm_u8 1ch 8000Hz)
AO: [alsa] 96000Hz mono 1ch u8
A: 00:00:16 / 00:00:17 (90%)
[ffmpeg/demuxer] wav: Packet corrupt (stream = 0, dts = NOPTS).
A: 00:00:17 / 00:00:17 (98%)
Exiting... (End of file)
localhost ~ # |
See, recording is only 8000Hz, which I guess is pretty low

stefan11111,
It's better and less bloated than PulseAudio
I forgot to set the dbus daemon, just turned it on again.
As you can see I already have
| Code: | CONFIG_SND_USB_AUDIO=y
CONFIG_SND_USB_AUDIO_MIDI_V2=y |
set
