[alsa-devel] Trouble with sound over HDMI with Nvidia MCP7A HDMI
by Austin Robertson 03 Jan '10

03 Jan '10

I am having trouble getting sound over hdmi with my Nvidia MCP7A HDMI. The strange thing is that everything works fine in a Live disc, but once I do a fresh install of that Live disc I get no sound, even though my configuration is exactly the same (as far as I can tell). I've checked the little things like alsamixer volumes, aplay -l, etc etc. Everything looks good to me. I can reproduce on multiple TVs so its not the receiver. Video drivers are the same in both live version and installed. aplay -l detects my device. sound/pci/hda/patch_nvhdmi.c already has my correct vendor id in it. Perhaps the following info can help figure out what my installed environment is lacking. I've been at it for days now and I'm stumped! Any ideas? *Live Disc Info* XMBC Live 9.11 (basically a optimized version of Karmic configured to start XBMC, or Xbox Media Center, see http://www.xbmc.org for more info) NOTE: My problem is not specific to the XBMC program. Things like aplay and speaker-test don't work either. *Hardware* Acer Aspire Revo R1600 http://www.newegg.com/Product/Product.aspx?Item=N82E16883103228&Tpk=AR1600 *XBMC Live installed to hard disk via Ubuntu installer* (This setup gives me no sound over HDMI) (This is a fresh install. No additional changes were made) alsa-info.sh http://www.alsa-project.org/db/?f=ab7cef7c7233f8c42756d36e362df684b9147d38 xbmc@XBMCLive:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 xbmc@XBMCLive:~$ aplay -L default:CARD=NVidia HDA NVidia, ALC662 rev1 Analog Default Audio Device front:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Front speakers surround40:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers hdmi:CARD=NVidia,DEV=0 HDA NVidia, NVIDIA HDMI HDMI Audio Output null Discard all samples (playback) or generate zero samples (capture) * ### speaker-test executes but NO SOUND over hdmi*. *I've also tried other devices like -D hdmi:0 -D hw:0,3 -D hdmi -D plug:hdmi, etc, etc* xbmc@XBMCLive:~$ speaker-test -D plughw:0,3 -c2 speaker-test 1.0.20 Playback device is plughw:0,3 Stream parameters are 48000Hz, S16_LE, 2 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 64 to 16384 Period size range from 32 to 8192 Using max buffer size 16384 Periods = 4 was set period_size = 4096 was set buffer_size = 16384 0 - Front Left 1 - Front Right Time per period = 5.637709 0 - Front Left xbmc@XBMCLive:~$ cat /proc/driver/nvidia/version NVRM version: NVIDIA UNIX x86 Kernel Module 190.53 Tue Dec 8 18:51:41 PST 2009 GCC version: gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu8) * XMBC Live Disc * ** (This setup gives me audio over hdmi perfectly) (This is running as a Live disc, ie not installed) ** alsa-info.sh http://www.alsa-project.org/db/?f=c95bebdc433f15147fb0be415be4e61e4d0b72ad [ ^<http://www.alsa-project.org/db/?f=c95bebdc433f15147fb0be415be4e61e4d0b72ad> ] xbmc@XBMCLive:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 xbmc@XBMCLive:~$ aplay -L default:CARD=NVidia HDA NVidia, ALC662 rev1 Analog Default Audio Device front:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog Front speakers surround40:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=NVidia,DEV=0 HDA NVidia, ALC662 rev1 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers hdmi:CARD=NVidia,DEV=0 HDA NVidia, NVIDIA HDMI HDMI Audio Output null Discard all samples (playback) or generate zero samples (capture) ###* speaker-test plays audio over hdmi perfectly. other programs play audio over hdmi.* xbmc@XBMCLive:~$ speaker-test -D plughw:0,3 -c2 speaker-test 1.0.20 Playback device is plughw:0,3 Stream parameters are 48000Hz, S16_LE, 2 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 64 to 16384 Period size range from 32 to 8192 Using max buffer size 16384 Periods = 4 was set period_size = 4096 was set buffer_size = 16384 0 - Front Left 1 - Front Right Time per period = 5.638693 xbmc@XBMCLive:~$ cat /proc/driver/nvidia/version NVRM version: NVIDIA UNIX x86 Kernel Module 190.53 Tue Dec 8 18:51:41 PST 2009 GCC version: gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu8) *Additional Information * I had an idea to run a diff on the two alsa-info.sh outputs of my installed and live version. (non-working and working, see above) I figured that might give me a clue on what I was missing. Most things should be identical with a few exceptions like timestamps, etc. MacBook-Austin:Desktop Austin$ diff -crB alsa-info_installed.txt alsa-info_live.txt > alsa-infodiff.diff alsa-info_installed.txt: http://pastebin.com/f63afa045 (non-working, same as above) alsa-info_live.txt: http://pastebin.com/f7b47d46d (working, same as above) alsa-infodiff.diff: http://pastebin.com/f79cf9c15 Only a few things caught my attention. At first I thought I had my playback volumes muted (line 525,532) according to the diff. But then I realized that was just for the mic, so that shouldn't matter. The only other thing that I saw was that my Amp-Out vals differed (line 123, 129). Perhaps, a more trained eye will have better luck.

[alsa-devel] Cross-compile problem with alsa-driver version 1.0.22
by Jie Jiang 03 Jan '10

03 Jan '10

Hi all, Recently I downloaded alsa-driver 1.0.22 and tried to build for i.MX27 platform. The "INSTALL" file enclosed in this release requires "--with-cross=arm-linux-" configuration option to cross-compile alsa driver for this ARM platform. Here is my build process #./configure --with-cross=arm-linux- --with-kernel=/home/working/bsp/Kernel/linux-2.6.19.2 --with-build=/home/working/bsp/ Kernel/linux-2.6.19.2 --with-moddir=/home/working/bsp/tmp --with-debug=full --enable-dynamic-minors --with-cards=all checking for gcc... arm-linux-gcc checking for C compiler default output file name... a.out checking whether the C compiler works... configure: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details. It seems that "--host=arm-linux" should be provided to configure script. However, when given the --host option, in the generated "Makefile.conf", I saw the following outputs, which are very confusing: NEW_KBUILD = mainsrcdir = . MAINSRCDIR = /work/63/alsa/alsa-driver-1.0.22 CROSS_COMPILE ?= arm-linux- ARCH ?= ifdef NEW_KBUILD CC = $(CROSS_COMPILE)arm-linux-gcc CPP = $(CROSS_COMPILE)arm-linux-gcc -E export CROSS_COMPILE ARCH else AS = $(CROSS_COMPILE)as LD = $(CROSS_COMPILE)ld CC = $(CROSS_COMPILE)arm-linux-gcc CPP = $(CROSS_COMPILE)arm-linux-gcc -E AR = $(CROSS_COMPILE)ar MODFLAGS = -DMODULE=1 CFLAGS_KERNEL = GENKSYMS = /sbin/genksyms -k 0.0.0 endif Obviously, the CC and CPP variables are not expected as "arm-linux-gcc". (There is one more $(CROSS_COMPILE)!) I overcome this problem by providing CC and CROSS_COMPILE variables with configure script: CC=gcc CROSS_COMPILE=arm-linux-gcc ./configure --with-cross=arm-linux- --with-kernel=/home/working/bsp/Kernel/linux-2.6.19.2 --with-build=/home/working/bsp/Kernel/linux-2.6.19.2 --with-moddir=/home/working/bsp/tmp --with-debug=full --enable-dynamic-minors --with-cards=all Then things become OK. What's wrong with the "INSTALL" file? Another problem. Even if "--with-cards=all" is given, codes in soc/codecs, soc/imx, and many other subdirs are not built. Is this because my target kernel version is too low (2.6.19.2)? It seems that the configure script sets some variables according to the kernel version and target platform and outputs into "toplevel.config". Is it possible to manually edit "toplevel.config" file (after configure process) to get soc/codecs, soc/imx codes compiled? Regards, Jie
