[Bug 262301] New: After running (unknown), festival fails with "Linux: can't open /dev/dsp"
https://bugzilla.novell.com/show_bug.cgi?id=262301 Summary: After running (unknown), festival fails with "Linux: can't open /dev/dsp" Product: openSUSE 10.2 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Sound AssignedTo: tiwai@novell.com ReportedBy: robin.listas@telefonica.net QAContact: qa@suse.de After running an unknown app, festival fails with this message: nimrodel:~ # echo "Hello" | /usr/bin/festival --tts Linux: can't open /dev/dsp I say "unknown because at first I thought it was amarok. Now I think it is Firefox - go on reading. However, sounds sent to the PCM interface (ie, DSP) work fine: nimrodel:~ # play /usr/share/sounds/au/crash.au nimrodel:~ # If I restart amarok or xine they play fine. And it doesn't show as busy: nimrodel:~ # lsof | grep dsp nimrodel:~ # however, an absurd command like this: nimrodel:~ # echo "Hello" > /dev/dsp -bash: /dev/dsp: Device or resource busy shows it is indeed busy; but by whom? I'm running as normal user under gnome, but you see I tried as root on an xterm. Restarting alsa solves the problem: nimrodel:~ # rcalsasound restart Shutting down sound driver done Starting sound driver: intel8x0 done nimrodel:~ # echo "Hello" | /usr/bin/festival --tts nimrodel:~ # (as a side note, restarting alsa crashed my firefox and I had to write this report twice). [...] Now, I think that note is important. I was reviewing this report before submitting, and noticed that amarok is not the culprit (or not always). It must be Firefox, because that would explain why it crashed when shutting down alsa: it must have been using sound in one of the pages I had opened, but I don't know which! It was silent. I will submit this and try again - if I don't submit and it crashes I loose the posted data. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=262301 ------- Comment #1 from robin.listas@telefonica.net 2007-04-07 06:42 MST ------- It indeed is Firefox the culprit. After viewing your video at <http://www.novell.com/linux/meetlinux/>, festival fails, till the page is closed. If not closed, festival continues to fail even if the video is not playing. If I restart alsa, festival works again: nimrodel:~ # echo "Hello" | /usr/bin/festival --tts Linux: can't open /dev/dsp nimrodel:~ # rcalsasound restart Shutting down sound driverERROR: Module snd_intel8x0 is in use ERROR: Module snd_ac97_codec is in use by snd_intel8x0 ERROR: Module snd_ac97_bus is in use by snd_ac97_codec ERROR: Module snd_pcm is in use by snd_intel8x0,snd_ac97_codec ERROR: Module snd_timer is in use by snd_pcm ERROR: Module snd is in use by snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer failed Starting sound driver: intel8x0 done nimrodel:~ # echo "Hello" | /usr/bin/festival --tts nimrodel:~ # echo "Hello" | /usr/bin/festival --tts nimrodel:~ # But firefox crashes: cer@nimrodel:~> firefox & [1] 11796 cer@nimrodel:~> ** (Gecko:11803): WARNING **: Owner of /tmp/orbit-cer2 is not the current user Flash Player: Warning: environment variable G_FILENAME_ENCODING is set and is not UTF-8 Flash Player: Warning: environment variable G_FILENAME_ENCODING is set and is not UTF-8 /usr/bin/firefox: line 160: 11803 Killed LD_PRELOAD=/usr/$LIB/libaoss.so${LD_PRELOAD:+:$LD_PRELOAD} $MOZ_PROGRAM $@ [1]+ Done firefox (note: the "Gecko:11803" warning above is Bug #246956) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Firefox is using esd for sound output. What you might see here is the Flash plugin or another plugin which tries to access /dev/dsp directly. I don't know the internals of libaoss.so but I would expect that this shouldn't happen when libaoss.so is used because concurrent access to audio out is the target of using libaoss.so at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

Why and what is at fault, I have no idea (firefox, flash, festival, whatever...) Re #3: Doesn't work.

And if aoss is not used you get a good error message "Linux: can't open /dev/dsp". this is not a bug from festival. festival simple do not support this. And if festival can't get lock of /dev/dsp something else has the lock. imho it's not usefull that festival says a text while a video is playing. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
