Can not Open Stream in PortAudio Library. Error: Invalid sample rate

0

Hello,

wireshark Version 1.4.2

My system hardware and audio device:

HP 210 Mini
Fedora 14
2.6.35.10-74.fc14.x86_64
 cat /proc/asound/cards
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0x56200000 irq 46

00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)

When I try and play back the rtp after making a sip call. I go to VOIP Calls | Player | Decode | Play. I get the following error message.

Got this info from PortAudio Library:
 Default hostApiName: ALSA
 Default deviceName: HDA Intel: STAC92xx Analog (hw:0,0) (0)

Can anyone suggest a solution to this problem?

Many thanks for any advice,

The Audacity audio device info gives the following picture:

  • Wireshark/PortAudio uses the default host api, which is ALSA
  • Wireshark/PortAudio uses the default device, which doesn't exists (weird bug)
  • Wireshark learns there's no device, starts enumeration.
  • Wireshark/PortAudio selects the first host API, ALSA
  • Wireshark/PortAudio selects the first device, HDA Intel: STAC92xx Analog (hw:0,0)
  • Wireshark/PortAudio opens a stream: Stereo, 16 bit, 8kHz
  • As you can see from the Audacity audio device info this device doesn't support rate 8000
  • Wireshark gives up

How to change the ALSA configuration to give you the right device as the first one I don't know.

The very best way is to put pressure on the PortAudio developers to fix the three years outstanding CRITICAL bug (*)

(*) Yeah it's a rant, but it must be solved at the source, not be worked around by all (audio) developers...

Thanks for your help. Just unfortunate that is no final solution.

Ehm, no, it's not a final solution. What would be is (in order of preference):

  1. A fixed PortAudio
  2. An even more exhaustive search by Wireshark for a usable device
  3. Create a user configuration option
  4. Have you work on the ALSA/device driver configuration or code

All of which requires developer cycles.

There's something off with the configuration of your audio system.

First off, the PortAudio library has some issues finding your default device, on the default host API. That's a PortAudio lib problem by itself, but Wireshark tries to work around it looking for other host API/device configurations.

It tries to work through the list of host APIs, the first one with devices on them is selected, then the first device on that is selected. An output stream is opened on it, with stereo output, 16 bit samples, 8 kHz sample rate.

Now, your title says: "Invalid sample rate". That strikes me as odd, because the output configuration is trivial in itself.

You could investigate further installing Audacity, and checking how it works the output host API/device options.

Hello, thanks for your answer. However, installing audacity didn't work. I installed it and then rebooted. See my edited question of the results. Thanks.

What does Audacity menu Help|Audio Device Info show ?

Hello Jaap, I have edited my answer with the device info. Thanks.
