usb audio works only after reinserting after boot

Tue Aug 28, 2012 7:37 am

Hello,
I am using a generic USB sound card (Quantum). The card is detected correctly on boot and aplay -l shows it.
But when I try to play a .wav file
aplay -D plughw:1,0 WELCOME.wav
it takes a while and prints out a lot of data about the file and one of the lines is
aplay: set_params:1145: unable to install hw params:
and there is no sound from the usb sound card.

Now if I remove the USB sound card and reinsert it, everything works OK.
This is a problem as the application has to work from power on unattended.

What could be wrong?

My OS Debian Wheezy 16-7-2012 .
I tried
apt-get update
apt-get install alsa-utils -> this says everything is uptodate

Thanks for any help.

Update:
After help from another thread (ALSA on Raspbian) I figured out that the USB sound card works OK with only the keyboard connected. It does not work at boot time if a USB hub to which a keyboard and mouse are connected. Problem seems to be with the usb stack of the OS or something to do with loading of the 5V supply.

I started seeing this issue after rpi-updating to the recent overclock-friendly setup w/ the 'turbo' and 'high' modes.... e.g.

Code: Select all

rpi3-11-~> vcgencmd version

The fix for plugging and unplugging the PS3 Eye camera did indeed enable audio. If using the system after a fresh boot w/ same webcam plugged in, you get

Code: Select all

arecord: pcm_read:1801: read error: Input/output error
After unplug/plug, I can successfully watch the audio level using:

Code: Select all

arecord -vv /dev/null -r 16000 -f S16_LE -c 4 -D iec958:CARD=CameraB409241,DEV=0 /dev/null < /dev/null
And even better after setting up ~/.asoundrc,

Code: Select all

## Suggested by http://julius.sourceforge.jp/forum/viewtopic.php?f=9&t=66
pcm.array {

  max_dB 5.0
}

pcm.cap {

I can just record a single channel that is summed via alsa's softvol plugin

Code: Select all

## see 'pcm.cap' defined in .asoundrc which sums 4 channels from Sony PS3 Eye camera into one
arecord -vv /dev/null -D cap -r 16000 /dev/null < /dev/null
Which shows the ALSA plugins a summin' (as to whether this is more or less efficient than not summing and just recording 4 channels, TBD):

Is the issue perhaps because the USB webcam soundcard ALSA initialization happens before the main ALSA initialization:

Re: usb audio works only after reinserting after boot

Mon Dec 10, 2012 6:12 am

I have a similar problem capturing audio with my USB PS3 Eye camera. The camera works fine, but the audio doesn't record unless I unplug the usb connector and plug it back in. Then it magically works.

To be more specific, after a reboot,
arecord -vv -f dat -D plughw:1,0 test.wav makes a 44 byte file every time. No recoding. The -vv option is supposed to dump a lot of info and then shows a little level meter. The info appears, but the level meter never does.

After unplugging and re-plugging in the usb cable, the same command above works great. Level meter appears and works. The dumped info is identical to what I get with the command before the unplug/replug.

I've tried mucking with /etc/modules, /etc/asound.conf, resetting the USB from software, and lots more stuff all to no avail. I can't figure out how to avoid pulling the USB plug and putting it back in again.

Has anyone overcome this problem? Thanks!

Hey guys! I'm brand new to the Pi scene and just created my account for this specific issue. I'm using a Pi to monitor noise levels using a Samson C01U microphone. I wrote a Perl script that records a second of audio using arecord then uses sox to analyze it for maximum amplitude and stores that into a SQLite database. I'm experiencing this exact issue. Namely, if I boot the device with the microphone attached then I get the error listed by other users. If I unplug/replug it then it suddenly works - but not reliably. After reading from it a few hundred times it suddenly does it again.

Code: Select all

[email protected] ~ $ arecord -d 1 -D hw:1 -c 1 -vvvv -f cd --file-type wav > file.wav

Clearly this is a system wide issue, there are very much different audio devices. I wonder what the common ground is between these?

I'm having this problem with a PlayStation Eye camera as well (with a Raspberry Pi Zero W running Jessie). The mic works fine if plugged in after boot or if plugged in on boot from power off, but if I reboot the Pi with the mic plugged in, it fails (arecord never stops recording, even if a duration is specified) until I unplug and replug it. The mic is reported by alsa as an available device even when it isn't working.

I've tried resetting the USB device using https://gist.github.com/x2q/5124616, but no dice: it reports a successful reset but the mic still doesn't work. I'm tried forcing alsa to reload, but that also doesn't seem to work. Not sure where to go from here :/

nobody found any solution after more than a year later ??
if there is a method to unplug and plug using script/software, then might be the solution

Re: usb audio works only after reinserting after boot

I have a similar problem with my USB audio device: unrecognized upon reboot, then recognized if unplugged and plugged back in. The only interesting part is that the problem for me occurs with the Pi Zero W. When I try to do the same with a Pi 3b (same configuration/settings), it works just fine after a reboot.

Was anyone able to find a solution or workaround?

I'm having similar problem with these speakers: https://www.adafruit.com/product/3369

I'm using a Raspberry Pi Zero W with Raspian Stretch Lite Kernel 4.14

Looks like the root cause is the usb speakers down get autodiscovered after reboot. If I do a reboot and do a lsusb this is what I get:

Code: Select all

[email protected]:~ $ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
And after I unplug and replug in the usb cable, then look at the usb devices:

Code: Select all

[email protected]:~ $ lsusb
Bus 001 Device 002: ID 1908:2070 GEMBIRD
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Does anyone know how this auto discover works (assuming the unplugging and replugging is some sort of autodiscovery)? Is there a way to trigger this discovery from a bash file or at startup?

Any help would be appreciated. Thanks.

I'm also having these problems and it's very hard to identify the cause, it doesn't seem to be an ALSA problem but related to USB.

It happens with the combination of the above Mini speaker: https://www.adafruit.com/product/3369
and respeaker or the playstation eye microphone, I'm getting:

I have no idea which of the items causes this, but it might be the Mini Speaker

Can anyone help us?
