From: Pavel Machek on 14 Mar 2010 04:00 Hi! In 2.6.33, hitting ^Z stopped mpg123 in a way you'd expect (both on thinkpad and geode notebook). On 2.6.34-rc1, hit ^Z and sound starts looping.

But it only happens a few times a year, so I never chased it. I hate to report an occasional problem in an obsolete kernel, and I can't reproduce it. Does it happen repeatably with the new kernel? -- Bill Davidsen <davidsen(a)tmr.com> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Is it an OSS app using the kernel OSS emulation or another backend? The possible cause is the rewrite of PCM hwptr updater. Jaroslav, could you take a look? thanks, Takashi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

OSS kernel emulation, yes. ... at least I think I'm using it. > The possible cause is the rewrite of PCM hwptr updater. > Jaroslav, could you take a look?

I cannot reproduce this problem here. Could you post the contents of /proc/asound/card0/pcm0p/sub0/status file when you stop the audio process and looping starts?
