Connecting the guitar jack cable to the microphone input (or line in) and listen it by the speakers or headphone. Right now I need to open a terminal write alsamixer and unmute the microphone because I didn’t find enything related in pavucontrol or in any GUI.

My current pulseaudio setup routes my sflphone ring sound to the headset instead of my speakers (even if I change the output while its ringing). I only care about pulseaudio 2.0 if this is fixed.

$ pulseaudio --version pulseaudio 2.0.0-1.mga2

Running fine on Mageia 2 RC, thanks for all the work! :)

Hopefully it can make it in an update, though!

We are pretty careful to make sure API/ABI is no broken. Clients should just work without modification with newer versions.

At some point we might break API in order to improve things, but this will be announced very loudly and clearly. :)

It depends very much on your hardware. I’d eventually like to see ALSA hand over this functionality to userspace and then have PulseAudio enable/disable outputs as per policy. This would allow you to do what you want if your hardware supports it.

You need CONFIG_SND_KCTL_JACK

Sorry, I don’t understand — what precisely are you trying to do?

I wish this was in Fedora 17, but given that it is released in 10 days, I doubt that will be the case :(

This does not seem to be mentioned anywhere but did the API/ABI change for clients? Or will older clients (that use PA directly) just work without a need for patiching / recompile?

About the jack detection, could it be possible in the future to use laptop speackers instead of headphones even when jack is connected or is this limited by the hardware? I guess using both at the same time is completely out of the question.

What kernel config options are required to make use of Jack detection?

Is possible to unmute microphone without use alsamixer and use pulseaudio like a guitar amplifier?

Arun,

Thank you for the quick response.

We do have the possibility to control all the bits on at least one device as long as the codec works with standard Wi -Fi hardware. We will be serving on a VPN and can develop protocol to suit the application. Our Wi-Fi delivery is already suited for high density and we can dedicate gigabit AP's as required.

The delivery of the data via Wi Fi is under our complete control and we also have the ability to control certain functions of the handsets circuitry and software from a dynamic application controlled by our server in real time depending upon the ability of certain handsets.

I believe that you would find this product and service possibly an exciting opportunity to develop Pulse Audio in supporting a newly granted and unique United States patent for delivering streaming live music content directly to cellphones at a concert in real time.

Please contact me directly so we may discuss the possibilities. I look forward to speaking with you.

Kind regards Frank Simon Sound at TheAudioAuction dot com

Great work Arun!..plz do post the latency results once get around to it..audioflinger latency is killing me right now..can’ wait to try dis out once the PA access via NDK is up..Awesome work again!

You can send audio over Bluetooth using Advanced Audio Distribution Profile, supported by most Android devices. Here's a post about setting up Linux PulseAudio to receive it. There's an apt-X codec for better audio quality supported by some Bluetooth implementations.

Another way to stream audio is the complexity and interoperability roulette of DLNA. I had some luck sending audio from my Android phone using the subpar iMedia Share DLNA app to a PlayStation3 (Digital Media Player -> DM Receiver), but had lockups trying to browse the phone's tracks from the PS3 (DM Server -> DM Controller?). There are DLNA feature packages for GStreamer and PulseAudio that supposedly can do similar things, but it wasn't obvious to me how to configure Kubuntu for them so I stuck with the low-tech cable with 3.5mm jacks :-)

mmm RC’s? the new algorithms implemented in Pulseaudio 1.1? I spend all day “fighting” with Pulseaudio 1.1 in Ubuntu 10.10 (by default is installed Pulseadio 0.9, and it hasn’t echo cancellation). But really I still have some problems… I have many sound cards devices connected to the laptop, in ALSA always start them in the right order (by /etc/modprobe.d/alsa-base.conf), but in Pulseaudio some times, some sound cards are not detected, and in the other hand, the another problem is that I write in /etc/pulse/default.pa the module-echo-cancelation for loading it… but the module is not loaded… I need to write in a terminal the instruction later have been started Ubuntu. I guess the problem is that Pulseaudio 1.1 is not the default of Ubuntu 10.10.

If you want, say, to have all the audio from a single app streamed to a remote machine yes. There are likely apps to do this already, and if not, you could use PA in the NDK to build an app to do this (I'll make my work usable from the NDK at some point in the not-too-distant future).

If you want to stream audio from arbitrary apps, I don't know of a simple way to do this other than the stuff that I am currently working on.

Hi Frank. This depends a bit on the actual cell phone on the other side (do you control the stack?) and the various pieces in between on your stack as well as how stable the wifi connection is.

There are various pieces that need some attention to get them to work better. For example, latency reporting for the tunnel sinks is a bit broken. And while we do have an RTP module for streaming remotely, there is no packet loss concealment as part of this.

So to answer your question -- if you have control over all the bits from start to finish, it is doable, but everything is not production-ready today.

Sounds like the echo-cancel module should suit your purpose. The current RCs have significant improvements in the quality of echo cancellation so you might want to try that out.
