Re: USB audio on RPi

Alan Melia
 

Could this be the same problem as surfaced with the original Funcube SDR receiver software. Here I believe dropped frames were due to drift between the two clocks (PC and USB "unit") Details may be found describing the symptoms and solution on the Funcube Yahoo Group.

Kristoff,

I've experimented with audio and fldigi on two original RPi's, but I
don't have a rev 2 to help answer your question. There is definitely
an ongoing and serious problem with USB on the RPi, though.

I would like to characterize the performance of several audio
devices. How to do you measure the number of frames dropped? Is
there a service in linux that gives this information?

Thanks,
Michael KD4SGN

Hi,



As has been discussed and published a number of times on the net, there
seams to be a pretty serious problem with USB on the RPi, which has its
effects on using an USB audio-dongle on it.
From what I have found, it seams to be related to using a USB 1.1
device on the (USB 2.0) HUB of the Pi.

Thanks!  I'll get a separate Pi for this and be ready for first run.

There is a fair bit of info on the TNC in this group's message archive, but to summarize, the TNC will be supplied by John Hansen W2FS, the maker of the TNC-X, and will be available, probably via the TNC-X website, in both kit and ready made form. Price and delivery aren't yet finalised, but I expect the kit to be in the $40-50 range, and availability in a few weeks.

Re: USB audio on RPi

Total beginner here but I want to help get this going.

This has been my experience sofar:
- When I just plug in a USB audiofob on the RPi, I seams to be loseing
audio-frames during audio-capturing. The number of frames dropped per
second does differ quite a lot per device. On some devices (like a USB
headset), I only have 17 to 18 audio-frames of 40 ms per second (instead
of 25).

- One trick seams to be to boot the Pi with the option set to limit the
USB speed to USB 1.1).

However, this seams to have a number of issues:
- in some cases, USB does not work anymore. E.g. my USB keyboard does
not work anymore.
- I had rapports of people where there are problems with the video
- When I use this trick and have 2 audio-devices active (both running at
48 Kbps full-duplex) at the same time, I have problems that the devices
says it does not have sufficient bandwidth for both sessions.
I find this a bit odd as USB 1.1 is -as far as I know- 12 Mbps and even
if you take the worse-case senario (2 * full-duplex stereo, 48 Khz
sampling, 16 bits/sample), I only have 3 Mbps / second

I use my RPi for developing the the c2_gmsk modem (codec2-based GMSK
modem for VHF and UHF), so I do need two audio-connections (one for the
headset for the user and one for the GMSK modem connection to the radio).

What is the experience of people on this group about this?

Some question:
- is there somebody who has a revision 2.0 version of the RPi. Does it
also have this USB issue?

- Has somebody ever tried this with a USB 2.0 audio-device? As far as I
read, the problem with the USB-bus is related to using a USB 1.1 device
on the USB 2.0 bus. So does using a USB 2.0 device help?

I just know I'm going to have $400 in this "cheap" computer after all is running.  Ohh well it will all be inside the go box and running on DC with the radios.  No wall warts to plug into a noisy inverter then into a gen set.
I plan to have most everything running on a solar bank and a 110AH gel cell.  We will see!

I'll check out that maker site as well.  Thanks!

You're not going to be able to pass 1 or 2 million I/Q samples per second over the " internet"; the solution I posted only enables you to send the I/Q data via your personal LAN (i.e. to other devices connected directly to your router). If you're having trouble doing this, you may need to configure your router and/or open up the firewall on the client PC - this depends on the exact combination of hardware and software you are using. Typical ethernet troubleshooting may be required - starting with ping to see if the two machines can reach each other. Also be sure your client SDR application is configured to look for input from the correct address/port (i.e. the address and port that is displayed in the rtl_tcp signon message) In SDR# this is done by selecting RTL-SDR / TCP and entering the address if the Pi using the Config menu.

Ham Radio Deluxe has never supported sound over internet.
Most people use Skype.
Skype is total bloatware these days, though it used to be lean and mean,
it's also now owned by MS themselves, so how long support for non Windows
systems will remain, is anyones guess.

Linux has several good VoIP programs that could be used.

Windows also has the beutifuly small and good "IPSound". Google, and ye
shall find. (Change the default port it uses though, the default is
often probed by some particulaly nasty malware.)

Sadly, it's not suported any more, but it gives you a choice of codecs,
that you can change on-the-fly as your audio needs (near HiFi stereo, to
narrow band mono comm's channel) change, or available network resources
dictates. It's not Open Source, but you can after reading the help and
history files, then with some creative Googling, find the Open Source
IpPhone (I think) Source Forge project it was based on.

There was even one version that sort of supported CI-V commands to remote
control an Icom radio.

If I had the time, and C/C++ skill's, I'd love to pick up and run with
that app. It's just too good to let die. Making it (or something
similar) run on the Pi, would be good to have.
