[alsa-devel] trying to get an eleven rack to work
by David Alexander 23 Mar '12

23 Mar '12

Hi. I bought and would like to get an eleven rack interface to work. It is a usb gutiar amp emulator/audio interface. It is a avid/digi device that normal uses asio vendor specific drivers. When I plug it under Linux I get the following: ls -l /proc/asound/card1 total 0 -r--r--r-- 1 root root 0 2012-03-17 18:57 id -r--r--r-- 1 root root 0 2012-03-17 18:57 midi0 -r--r--r-- 1 root root 0

understanding is that it would require some additional coding in the quirks code for the snd-usb-audio driver. How can I determine what the quirks are? Does there exist any documentation or how-tos that I can look for on this? Any help or suggestions are appreciated. sincerely, David Alexander

I'm really sorry for taking so long - this is still an issue for me, but contrary to my expectations, I was not able to reboot this machine yet and it might take some more time (weeks...) before that's convenient. I will try the then-current kernel and for-next branch then.

[alsa-devel] [PATCH] [v3] powerpc/8xxx: remove 85xx/86xx restrictions from fsl_guts.h
by Timur Tabi 21 Mar '12

21 Mar '12

Remove the check for CONFIG_PPC_85xx and CONFIG_PPC_86xx from fsl_guts.h. The check was originally intended to allow the same header file to be used on 85xx and 86xx systems, even though the Global Utilities register could be different. It turns out that they're not actually different, and so the check is not necessary. In addition, neither macro is defined for 64-bit e5500 kernels, so that causes a build break. Signed-off-by: Timur Tabi <timur(a)freescale.com> --- The ASoC part of this patch applies cleanly to the ASoC for-3.4 branch, so this patch should not cause any merge conflicts if carried on the PowerPC branch, so I suggest that Kumar pick this up for 3.4 (it fixes a potential 64-bit book-e build break), with an ACK from Mark. arch/powerpc/include/asm/fsl_guts.h | 26 +++++--------------------- arch/powerpc/platforms/85xx/mpc85xx_mds.c | 2 +- arch/powerpc/platforms/85xx/mpc85xx_rdb.c | 2 +- arch/powerpc/platforms/85xx/p1022_ds.c | 4 ++-- arch/powerpc/platforms/86xx/mpc8610_hpcd.c | 2 +- sound/soc/fsl/mpc8610_hpcd.c | 8 ++++---- sound/soc/fsl/p1022_ds.c | 10 +++++----- 7 files changed, 19 insertions(+), 35 deletions(-) diff --git a/arch/powerpc/include/asm/fsl_guts.h b/arch/powerpc/include/asm/fsl_guts.h index ce04530..aa4c488 100644 --- a/arch/powerpc/include/asm/fsl_guts.h +++ b/arch/powerpc/include/asm/fsl_guts.h @@ -16,15 +16,6 @@ #define __ASM_POWERPC_FSL_GUTS_H__ #ifdef __KERNEL__ -/* - * These #ifdefs are safe because it's not possible to build a kernel that - * runs on e500 and e600 cores. - */ - -#if !defined(CONFIG_PPC_85xx) && !defined(CONFIG_PPC_86xx) -#error Only 85xx and 86xx SOCs are supported -#endif - /** * Global Utility Registers. * @@ -36,11 +27,7 @@ * different names.

[alsa-devel] [PATCH 0/3] ASoC: omap-mcbsp: Constraint handling changes
by Peter Ujfalusi 21 Mar '12

21 Mar '12

Hello, This series will add the following changes: 1. We do not need to place buffer size constraint in case of a capture stream. 2. Grazvydas Ignotas <notasas(a)gmail.com> reported that on Pandora they have issues with legacy applications (and OSS emulation) when they open the playback with small period size (smaller than the FIFO size). Since these legacy applications can not be fixed (and it is not feasible), this series will provide a solution to overcome with the underruns at the stream start. With the introduction of the new sysfs file (period_protection) the user can request the driver to place the constraint to the period size instead of the buffer size. With the period_protection one can specify the number of samples they want to have as protection in period size constraint over the McBSP FIFO size. As an example: OMAP3, McBSP2, stereo stream. the FIFO is 640 samples long. period_protection = 1 will ensure that the period size is minimum of 641 samples long. With the test code from Grazvydas Ignotas: http://notaz.gp2x.de/misc/alsa_period_test.c I don't see underrun issues with period_protection = 1 on BeagleBoard. Regards, Peter --- Peter Ujfalusi (3): ASoC: omap-mcbsp: buffer size constraint only applies to playback stream ASoC: omap-mcbsp: Restructure omap_mcbsp_dai_startup code ASoC: omap-mcbsp: Add period size protection mode sound/soc/omap/mcbsp.c | 2 + sound/soc/omap/mcbsp.h | 1 + sound/soc/omap/omap-mcbsp.c | 71 ++++++++++++++++++++++++++++++++++-------- 3 files changed, 60 insertions(+), 14 deletions(-) -- 1.7.8.5
