A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1823> ====================================================================== Reported By: darkbrain Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 1823 Category: PCI - cs46xx Reproducibility: always Severity: major Priority: normal Status: new Distribution: Kernel Version: ====================================================================== Date Submitted: 02-05-2006 22:59 CET Last Modified: 07-25-2006 16:03 CEST ====================================================================== Summary: surround40 memory leak Description: It seems that surround40 has a memory leak or somthing similar, playing a game in surround40 mode the game result unplayable after some minutes. And there is a problem in CS46xx.conf file, i need to remove the hook on the rear pcm to permit multiple surround40 subdevices to be opened. ====================================================================== ---------------------------------------------------------------------- darkbrain - 07-25-06 10:18 ---------------------------------------------------------------------- Well the problem is difficult to resolve. For hooks read better the description of the bug. Anyway i talked to Benny Sjostrand about these problems and he explained me a bit the logic of this dsp, and how this driver was made: throght reverse engineering! The only thing i've found is this: in file dsp_spos.c replace "REAR_CODECOUT_SCB_ADDR,codec_in_scb" with "REAR_CODECOUT_SCB_ADDR,codec_out_scb" at about line 1364. With this "patch" you should be able to use the quad pcm (route device) without the out of sync problem. Anyway the problem isn't solved! It maybe a delay in some SCB or it may be an application problem caused by the cut of available devices that is halved. Btw without documentation is not possible to work on it. bye, DarkBrain ---------------------------------------------------------------------- Raymond - 07-25-06 16:03 ---------------------------------------------------------------------- Do the "out of sync" problem occur even 2 or 3 instances of surround40 ? If yes, there is no way to fix unless you know how to patch the firmware. The available resource DSP_MAX_PCM_CHANNELS are not enough for 31 subdevices(instances) of surround40 or surround51 If there are only 2 pcm_channels left and pcm_multi try to open surround40 or surround51, it is possible that pcm_multi and cs46xx driver is not capable to recover from this kind of error. The au88x0 driver also have this kind of problem https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2228 The driver of the hardware mixing sound card need special handling in snd_xxx_hw_params() and snd_xxx_hw_free() for OSS emulation too.
