[alsa-devel] Swissonic TS22PCI / Teratec Phase 22 / driver problems with ice1724
by Manuel Schneider 14 Aug '08

Hi, we had a Teratec Phase 22 on our transmitter line which works great under Linux, using the ice1724 driver from alsa. As the original sound card broke due to electrical surge on the transmitter line, we had to replace it. The Phase 22 is not available anymore, so we bought a Swissonic TS22PCI which is based on the Phase 22: http://www.thomann.de/gb/swissonic_ts22pci.htm The PCB looks exactly the same as the Phase 22, but the driver does not initialize the card correctly: --- dmesg: ice1724: No matching model found for ID 0x3b157b11 ice1724: Invalid EEPROM version 0 AC'97 0 does not respond - RESET AC'97 0 access is not valid [0xffffffff], removing mixer. ice1712: cannot initialize pro ac97, skipped --- I already updated to Linux 2.6.25 and tried the current alsa-drivers package (1.0.17), but I get always the same errors in the kernel log. I also deleted /etc/asound.* and /var/lib/alsa/asound.state, ran alsa-conf - no luck. Do you have any ideas how I can get this card to work?

Hi all, I'm trying to bring up audio on powerpc AMCC 440EPX board with the soundcard Sound Blaster Audigy CA0106. The board is runing Ubuntu 7.04. I configured: ./configure --with-cards=ca0106 --with-sequencer=yes --with-kernel=/usr/src/linux Then I make and get issue: make[2]: Leaving directory `/root/alsa-driver-1.0.17/usb' make[2]: Entering directory `/root/alsa-driver-1.0.17/misc' make[2]: Leaving directory `/root/alsa-driver-1.0.17/misc' make[1]: Leaving directory `/root/alsa-driver-1.0.17' make -C /usr/src/linux SUBDIRS=/root/alsa-driver-1.0.17 CPP="gcc -E" CC="gcc" modules make[1]: Entering directory `/usr/src/linux' CC [M] /root/alsa-driver-1.0.17/acore/memory_wrapper.o make[1]: Leaving directory `/usr/src/linux' root@sequoia:~/alsa-driver-1.0.17# vim log In file included from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: /root/alsa-driver-1.0.17/include/adriver.h:278:1: warning: "GFP_DMA32" redefined In file included from include/linux/slab.h:14, from include/linux/percpu.h:5, from include/linux/rcupdate.h:41, from include/linux/pid.h:4, from include/linux/sched.h:76, from /root/alsa-driver-1.0.17/include/asm/elf.h:5, from include/linux/elf.h:7, from include/linux/module.h:14, from /root/alsa-driver-1.0.17/include/adriver.h:26, from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: include/linux/gfp.h:105:1: warning: this is the location of the previous definition In file included from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: /root/alsa-driver-1.0.17/include/adriver.h:828: error: static declaration of âjiffies_to_msecsâ follows non-static declaration include/linux/jiffies.h:270: error: previous declaration of âjiffies_to_msecsâ was here /root/alsa-driver-1.0.17/include/adriver.h:847: error: static declaration of âmsecs_to_jiffiesâ follows non-static declaration include/linux/jiffies.h:272: error: previous declaration of âmsecs_to_jiffiesâ was here In file included from /root/alsa-driver-1.0.17/include/adriver.h:944, from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: include/linux/pci.h:594: error: expected identifier or â(â before numeric constant In file included from /root/alsa-driver-1.0.17/include/asm/pci.h:8, from include/linux/pci.h:945, from /root/alsa-driver-1.0.17/include/adriver.h:944, from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: include/linux/mm.h:235: error: conflicting types for âsnd_compat_vmalloc_to_pageâ /root/alsa-driver-1.0.17/include/adriver.h:748: error: previous declaration of âsnd_compat_vmalloc_to_pageâ was here In file included from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: /root/alsa-driver-1.0.17/include/adriver.h: In function âsnd_pci_orig_save_stateâ: /root/alsa-driver-1.0.17/include/adriver.h:1186: error: too many arguments to function âpci_save_stateâ /root/alsa-driver-1.0.17/include/adriver.h: In function âsnd_pci_orig_restore_stateâ: /root/alsa-driver-1.0.17/include/adriver.h:1190: error: too many arguments to function âpci_restore_stateâ In file included from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: /root/alsa-driver-1.0.17/include/adriver.h:1552:1: warning: "page_to_pfn" redefined In file included from /root/alsa-driver-1.0.17/include/asm/page.h:150, from /root/alsa-driver-1.0.17/include/asm/thread_info.h:30, from include/linux/thread_info.h:35, from include/linux/preempt.h:9, from include/linux/spinlock.h:49, from include/linux/seqlock.h:29, from include/linux/time.h:8, from include/linux/stat.h:60, from include/linux/module.h:10, from /root/alsa-driver-1.0.17/include/adriver.h:26, from /root/alsa-driver-1.0.17/acore/memory_wrapper.c:25: include/asm-generic/memory_model.h:79:1: warning: this is the location of the previous definition /root/alsa-driver-1.0.17/acore/memory_wrapper.c: In function âsnd_compat_vmalloc_to_pageâ: /root/alsa-driver-1.0.17/acore/memory_wrapper.c:44: error: implicit declaration of function âVMALLOC_VMADDRâ /root/alsa-driver-1.0.17/acore/memory_wrapper.c:50: error: implicit declaration of function âpte_offsetâ /root/alsa-driver-1.0.17/acore/memory_wrapper.c:50: warning: assignment makes pointer from integer without a cast make[3]: *** [/root/alsa-driver-1.0.17/acore/memory_wrapper.o] Error 1 make[2]: *** [/root/alsa-driver-1.0.17/acore] Error 2 make[1]: *** [_module_/root/alsa-driver-1.0.17] Error 2 The issue looks like an error in alsa-driver source code.

[alsa-devel] ASoC machine driver: use more than one at91 ssc
by Simon Tremblay 14 Aug '08

14 Aug '08

Hi, I want to use more than one SSC (2 to be more accurate) to be able to do what is indicated at Figure 4 of page 10/13 of this document http://www.atmel.com/dyn/resources/prod_documents/doc6020.pdf (how to setup SSC with a I2S codec). I saw in sound/soc/at91/eti_b1_wm8731.c use of 1 SSC. Does I need more than one snd_soc_dai_link in my snd_soc_machine? But for what I understand for now, I need one SSC for sound output and 2 SSC for sound input. I don't know if there is some example about how to do that. Simon

[alsa-devel] alsactl init - implementation and more..
by Jaroslav Kysela 14 Aug '08

14 Aug '08

Hi, some developers probably already noted, I commited to alsactl utility (alsa-utils package) initial implementation of soundcard initialization stuff aka 'alsactl init'. The basic idea was to "reuse" nice udev configuration style and modify it to ALSA purposes. I hope that I ended up with a syntax which is easy understandable and configuration can be created with minimal effort. Please, look to 'man 7 alsactl_init' for more details and to alsa-utils/alsactl/init directory for example files. Note that the runtime evaluation of commands can be modified using environment variables like udev does. Just try 'alsactl -E CMD=help init' or 'CMD=help alsactl init'. Hardware can be detected using sysfs. For older kernel, I'm plannig to add some compatibility layer to read at least ATTR{subsystem_vendor} and ATTR{subsystem_device} information from procfs (codec files). Also, a way to gather working configurations for specific hardware is required. A nice script alsa-info.sh is already in the alsa-driver package, so I just created a simple persistent "file" dabatase on www.alsa-project.org: http://www.alsa-project.org/cardinfo-db/ and modified alsa-info.sh to use this database for the contents upload by default. Developers can download whole database in a tar package to extract necessary information using command line text tools and use this database also for other purposes (HDA codec graphing and so). More ideas, corrections, opinions are welcome. Jaroslav ----- Jaroslav Kysela <perex(a)perex.cz> Linux Kernel Sound Maintainer ALSA Project, Red Hat, Inc.

[alsa-devel] S24_LE Mode for USB Driver
by Charles Eidsness 13 Aug '08

13 Aug '08

Hi All, It looks like the parse_audio_format_i_type function at line 2369 of usbaudio.c (linux v2.6.23) doesn't support the case where bSubframeSize (fmt[5]) = 4 bytes and bBitResolution (fmt[6]) = 24 bits, which should correspond to a S24_LE (or BE) type. I'm developing a new USD DAC which supports this mode (24-bit sample in a 4 byte package). Right now Linux sends me S32_LE formated data, which is wrong. Would it be possible to expand this function to support S24_LE/BE? It would only require adding a few lines of code. Thanks! Charles
