Bug 100276 – ALSA-1.0.9 Latency issue with snd-ens1371, fps cube crashes

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Martin 2005-07-25 12:41:31 UTC]

After upgrade to ALSA 1.0.9 (lib, driver), sound with snd-ens1371 has several
100ms latency. Nasty in bzflag, noticeable with xmms, not noticeable with xine
playing dvd. fps "cube" crashes while starting. Problem is reproducible with
kernel 2.6.12-r4, 2.6.12-r6 and vanilla 2.6.11.12. Problem not affected by
IO-APIC option, HPET or in kernel-alsa or alsa-driver.
Problem does not affect the snd-via82xx driver, which is on the mainboard.

Reproducible: Always
Steps to Reproduce:
1. have 2.6.12 kernel running with alsa-1.0.9 and snd-end1371 as only soundcard
2. start a bzflag game OR
3. start cube
Actual Results:  
In bzflag, all sounds are some 100ms late and slightly disturbed.
cube crashes after starting "SDL parachute deployed"

Expected Results:  
work as with snd-via82xx, e.g. no noticable latency, cube not crashing.

Maybe bug #94577 is induced by this fault.

Please provide emerge --info.  I've got that card in my sparc box, and it's
working great for me with 1.0.9b driver and 1.0.8 lib.  Can you try downgrading
alsa-lib.

[Comment 2 Martin 2005-07-27 10:52:48 UTC]

With alsa-lib-1.0.8 bzflag works OK with snd-ens1371; xmms has no noticeable 
latency. cube still crashes (I have to say I installed cube separately from a 
tarball and precompiled binary):

[Comment 3 Jeremy Huddleston (RETIRED) 2006-03-31 22:27:53 UTC]

Sorry for being away for so long... is this still noticible with a 2.6.16 kernel and its builtin alsa modules?  What about alsa-driver-1.0.11_rc?

[Comment 4 Jakub Moc (RETIRED) 2006-08-15 03:31:39 UTC]

Please, test w/ alsa-driver-1.0.11 and current kernels, as requested above.

[Comment 5 Martin 2006-08-18 07:20:47 UTC]

Just switched from in-kernel alsa to alsa-driver-1.0.11. kernel is 2.6.17-r4.

bzflag: sound stutters with relatively high frequency (5-8/s, shots sound like machine gun).

cube: starts and plays sound as expected.

amarok plays sound as it should.

had no time yet to test via-driver or in-kernel alsa with snd-ens-1371.

[Comment 6 Martin 2006-08-18 10:47:26 UTC]

Switched to via82xx and alsa-driver, sound in bzflag is normal again. semms to be driver-specific.
