Jack Server Not Running

SSébastien posted Oct 17, 11:01: I was wandering if the problem was coming from pyaudio with my DAC, but with a simple example, I can play a file from a python I mean, after 11488 bytes transfered it's still ok but when trying to send another 5744 bytes, it locks up. I can probably find out Monday from the author.(although at the moment I think vchiq is behaving correctly, it's just the audio server task on GPU that blocks when its buffer Resampling by plug may be costlyIncrease the VC audio buffer size by a factor of 12 to handle 8kHz->48kHz resample, plus 8bit->16bit. http://popupjammer.com/unable-to/xfconf-isn-39-t-running.html

Perhaps also use it for resampling from <16kHz which is relatively cheap, and proably only used by low end games.Then buffer size only needs increasing by a factor of 3.This 352K An item in IEnumerable does not equal an item in List Do progress reports/logging information belong on stderr or stdout? I suppose a usb mic is recommended?

Or maybe we should use mmap_emul variant that will also allow plughw to work on >2 channels PCM (but the downside is bigger latency). Thanks very much for any help ! Is it something about alsa configuration or the port audio settings? Ioerror: [errno -9997] Invalid Sample Rate If so, what is it's content?

Now I have an error from pyaudio saying sample rate is invalid. Pyaudio Raspberry Pi When I use rec command to record "alexa" samples, even if I put "-r16000" variable, a warning will be shown and the samplerate is forced to be reset to 48000 then. Once the start command has been sent, there's no lockup but the bulk queue transmit might stall until samples are played out.This doesn't explain to me why it lock up at https://github.com/Kitt-AI/snowboy/issues/45 So it is not really ALSA related and it's VC fault that it don't confirm receiving data?I suspect that the information about supported sample rates (linear between 8000-48000) in bcm2835-pcm.c is

In the meantime you could probably try to use some other microphones?

use plug for 8bit->16bit which is cheap.

I'm getting 10s no matter what I set in asoundrc - plugw -> plughw, mmap_emul -> plughw or lfloat -> plughw. Is green led flashing? We have found here that adding this file (/etc/asound.conf or alternately ~/.asoundrc)Code: Select allpcm.!default {

God knows...

See below why: NOTE: You do not have to be currently using the pulseaudio sound server for flash websites work. If (say) resampling before passing to the hardware (or the pipe to the hardware) doesn't work either then it might suggest an "upstream" problem. This is why I had to spend so much time putting it there. his comment is here If you do not want to use pulseaudio, do not kill the process like I did :roll: That is the research I gathered from over 4 hours of tinkering with it.

Folder-by-type or Folder-by-feature If the Ch’in dynasty was so short-lived, why was China named for it? My device was never listed under the Pulseaudio Volume Control. The copy only occurs when VC is ready, so they are more likely to block.VCHI_FLAGS_BLOCK_UNTIL_QUEUED just means the buffer (pointer) has been added to the VCHIQ transmit queue, but hasn't necessarily Make sure you are able to record using rec test.wav, and make sure the recorded audio sounds good to you.

It's good to know how it works tho. Does a server socket need to be installed? How to exchange their device loading order?0Unexpectedly lost speaker output.
