Hi Clemens, > You could compare <http://manuals.opensound.com/devlists/Linux.html> > with ALSA's sound card matrix, but the latter tends to be out of date. > Yeah, that thing is oooooold. Hopefully the new wiki on't be too bad. > > With the recent open sourcing of OSS, it would be nice to port code > > to ALSA for devices that are only currently covered by OSS. > > AFAICS all devices supported by the open-source OSS are also supported > by ALSA. > Ah, looks can be deceiving. Although both systems have 'geode' support, it seems that the OSS driver supports the CS5530 VSA2 and the SC1200. Also, there's an open bug for the Neomagic 256 driver, which may have a solution hiding away in OSS somewhere (someone with the hardware is hopefully going to help me look into that). There's a couple of things right off the bat and I don't know ALSA very well at all compared to most of you. And yeah, I know this stuff isn't in great demand, but it'd be nice if people weren't able to say that OSS can do XYZ and ALSA can't. Ash -- Get a Free E-mail Account at Mail.com!

[alsa-devel] OSS/4Front
by Ash Willis 21 Jun '07

21 Jun '07

Hi, Does anyone know if there's any kind of list showing a comparison of hardware support between ALSA and OSS/4Front? With the recent open sourcing of OSS, it would be nice to port code to ALSA for devices that are only currently covered by OSS. There has to be at least a few devices that we can grab support for, right? It may at least provide us with insight into a few bugfixes. Ash -- Get a Free E-mail Account at Mail.com!

Hi all, first post for me. I have a Yamaha DS2416 mixer card and Yamaha SW1000XG sound card that I would like to use onLinux (Fedora 6). I have used them on the "other" OS, along with ProTools, etc. Does anyone know if Linux drivers are available? I have looked around, and it seems not to be the case. any help would bve appreciated.

[alsa-devel] No time for cs4624
by chris＠idlelion.net 21 Jun '07

21 Jun '07

I really wanted to work on the cs4624 suspend resume bug (#305), but there is no time, especially given the lack of technical information. I'm wondering if I were to lend or give a laptop that exhibits the problem to one of you alsa developers, if that would be useful and provide some impetus to fix the bug, or if it would just be a big pain? Opinions? Chris

[alsa-devel] Output levels on SBLive! 5.1 on ALSA vs WIndows
by ChernYue Kwok 20 Jun '07

20 Jun '07

Hello, I am using an SBLive! 5.1 sound card (emu10k1 chipset) with 6 channel output. Due to the nature of my work, I need to be able to play sound through all 6 channels at the same output level to an amplifier. Using Linux and the emu10k1 ALSA driver, I measured output voltage levels on an oscilloscope while playing a sine wave on all 6 channels, and I got three different output voltage amplitudes for the front, rear and center/subwoofer channels. Repeating the same test with the same card on WIndows using the Creative SBLive drivers from their website, I am able to get the same output voltage amplitude on all 6 channels. For both tests, all output levels in the relevant mixers were set to their maximum levels. I would like to know if this output normalizing 'feature' of the SBLive Windows driver can be found in the emu10k1 ALSA driver, or in any other ALSA driver. Failing that, is there any other solution to set output levels in the driver, or am I doomed to twiddle in alsamixer to get the output levels that I want? Thanks in advance.

[alsa-devel] Using aplay and arecord on an ARM
by Paul Kavan 20 Jun '07

20 Jun '07

Liam: I have managed to get the alsa-libs and aplay, arecord, and speaker-test on my board, but I am unsure how to get them to play. I have tried making the device nodes and am using a simple alsa.conf, but still no joy. I am sure there is something simple I am missing. Trying to find some documentation on this. I am assuming there is some disconnect between the interface and my conf file. I have my alsa.conf file in /usr/share/alsa/ and it is: pcm.!default { type hw card 0 } pcm.hw { type hw card 0 device 0 subdevice 0 } ctl.!default { type hw card 0 } ctl.hw { type hw card 0 } ctl.w6811 { type hw card 0 } pcm.w6811 { type hw card 0 device 0 subdevice 0 } ctl.!default = ctl.w6811 pcm.!default = pcm.w6811 ctl.hw { @args[ CARD ] @args.CARD { type string default "0" } type hw card $CARD } pcm.hw { @args[ CARD DEV SUBDEV ] @args.CARD { type string default "0" } @args.DEV { type integer default 0 } @args.SUBDEV { type integer default 0 } type hw card $CARD device $DEV subdevice $SUBDEV } I have some /proc/ entries: /proc/asound $ ls GRHEKW6811 cards pcm version card0 devices timers /proc/asound $ cat cards 0 [GRHEKW6811 ]: W6811 - GRH_EK_W6811 GRH_EK_W6811 (W6811) /proc/asound $ cat devices 0: [ 0] : control 16: [ 0- 0]: digital audio playback 24: [ 0- 0]: digital audio capture 33: : timer /proc/asound $ cat pcm 00-00: W6811 W6811-PCM-0 : : playback 1 : capture 1 /proc/asound $ cat timers G0: system timer : 10000.000us (10000000 ticks) P0-0-0: PCM playback 0-0-0 : SLAVE P0-0-1: PCM capture 0-0-1 : SLAVE /proc/asound $ cat version Advanced Linux Sound Architecture Driver Version 1.0.14rc4 (Wed May 09 09:51:39. Now, into GRHEKW6811 (which takes me to card0) I get a pcm0c and pcm0p directory. Using cat info, I get: /proc/asound/card0/pcm0c $ cat info card: 0 device: 0 subdevice: 0 stream: CAPTURE id: W6811 W6811-PCM-0 name: subname: subdevice #0 class: 0 subclass: 0 subdevices_count: 1 subdevices_avail: 1 /proc/asound/card0/pcm0c $ cd ../pcm0p/ /proc/asound/card0/pcm0p $ cat info card: 0 device: 0 subdevice: 0 stream: PLAYBACK id: W6811 W6811-PCM-0 name: subname: subdevice #0 class: 0 subclass: 0 subdevices_count: 1 subdevices_avail: 1 I then did: mknod -m 666 /dev/snd/pcm0p c 116 0 mknod -m 666 /dev/snd/pcm0c c 116 0 However, when I try speaker-test, I get: /usr/lib/bin $ ./speaker-test -D pcm0p speaker-test 1.0.14 Playback device is pcm0p Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM pcm0p Playback open error: -2,No such file or directory Same for default: /usr/lib/bin $ ./speaker-test -D default speaker-test 1.0.14 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise ALSA lib pcm.c:2144:(snd_pcm_open_noupdate) Unknown PCM default Playback open error: -2,No such file or directory When I try aplay -l and arecord -l, I get: /usr/lib/bin $ ./aplay -l aplay: device_list:204: no soundcards found... /usr/lib/bin $ ./arecord -l arecord: device_list:204: no soundcards found... I am at a loss here. Anyone have any advice, pointers, tips, etc...... Thanks.

[alsa-devel] ALSA always writes _whole_ periods, right?
by Joachim Förster 20 Jun '07

20 Jun '07

Hi ALSA devs, I have a quick question regarding the filling of the usual ring buffer in RAM (used by sound controllers via DMA), just to be really sure: Is it true, that ALSA always writes (via mmap'ing) _whole_ periods? I took snd-dummy and modified it to use "ack()" method and tried to confirm, if the above is true _without_ memory mapping (classical read/write). It seem's to be true, ALSA is "filling up" the last (not always complete) period - e.g. if the played wav file is not a multiple of periodsize in length. But well, with mmap, I cannot see the copying action (done by ALSA library, right?) ... so, thus my question ;-) . Thanks, Joachim
