The crashes are not so random any more. They happen every time when
music stops playing. This was not simple to find, because I use ALSA
with the dmix plugin (but without any sound daemon like ESD or
PulseAudio). Usually I pause my music (XMMS) and sometimes my browser
has some Flash applets running which also occupy the audio output. So
audio is not always stopped, when I hear it to stop.
So, I found out that when I start music (e.g. with a simple "aplay
xyz.wav") without any other program doing sound output, g15daemon is
automagically started by udevd. As soon as the music stops (^C to aplay)
g15daemon is stopped by udevd. I've set the
G15DEBUG="on"
in /etc/default/g15daemon and activated moderate debug output by udev
with
udevadm control --log-priority info
The output as observed in /var/log/syslog is attached in the two files
syslog-aplay-{start,stop}.txt.
It seems that every time aplay (or any other sound output) is running,
the device file /dev/usbdev2.3_ep01 is created. Endpoint 1 (OUT) is the
AudioStreaming isochronous endpoint. It seems that this "magically"
turns up upon audio output and vanishes afterwards. OTOH, according to
lsusb, the USB descriptor doesn't change at all in these two conditions
(see attached files lsusb-z10-{playing,silent}.txt), the only difference
is the "Report Descriptor" which seems cannot be queried during audio
output.
So, the first question is: Why does udev send "add" and "remove" events
just because an USB device is used although no endpoints are added or
removed?
The second question is: Why do the G15 scripts start and stop the
g15daemon for each of these events?
I've now added some more debug output on the udev environment variables
and found the following information when starting and stopping playing
audio output:
Sep 23 21:40:16 hansi g15: calling g15 udev; action: "add", product "",
devtype "", devname "/dev/usbdev2.6_ep01", subsystem "usb_endpoint"
Sep 23 21:40:17 hansi g15: calling g15 udev; action: "remove", product "",
devtype "", devname "/dev/usbdev2.6_ep01", subsystem "usb_endpoint"
It should be possible to add conditions to /etc/init.d/g15daemon to
avoid these problems. Additionally I think the additional "shared-udev"
parameter can be removed.
When the G15 speakers are plugged in and removed from the USB bus, the
debug output by /etc/init.d/g15daemon is as shown in the attached files
usb-{plugin,remove}-z10.txt (note that usb-plugin-z10.txt is partly
cluttered by a concurrently playing sound).
The unique removal event is
action: "remove", product "46d/a07/1e", devtype "usb_interface", devname "",
subsystem "usb"
while for the plugin of the speakers the devtype "usb_interface" event
is twice. So I suggest to use the following event:
action: "add", product "46d/a07/1e", devtype "usb_device", devname
"/dev/bus/usb/002/006", subsystem "usb"
Unfortunately a little delay is necessary because g15daemon wants to
open /dev/uinputX (or so) which will be populated shortly after this
event.
I've added these additional conditions to the script, see attached patch
etc-init.d-g15daemon.patch. With these changes g15daemon is not killed
any more and works flawlessly. But please check with other supported
devices. As already mentioned, I think that then the special
"shared-udev" parameter of the script can be removed.
Bye
Hansi
