[alsa-devel] non-interleaved mode
by Steve Longerbeam 11 Jul '07

11 Jul '07

Hi, The driver for the sound engine I'm working on requires NONINTERLEAVED. Will ALSA core give my driver a full period of left-only samples, followed by a full period of right-only samples? Or are left/right samples split within a single period (ie. first half of period is left samples, second half is right samples)? Thanks, Steve

[alsa-devel] Query regarding sampling rates etc
by Pharaoh . 11 Jul '07

11 Jul '07

Hi, This is a very vague question, just thought of asking it after hours of debugging. I am testing my alsa driver, written for omap 730/850 based board. I am testing it by using aplay. Despite checking clocks, sampling rates etc many times and after doing many combinations thereof, I cant hear anything more than a noise which changes and becomes more like the original .wav file as I change various params like sampling rates/clocks etc. It becomes close to the actual thing, but not better. Any idea what are the params I should be tweaking? I know this is h/w dependent. -pharaoh

[alsa-devel] Alsa lib configure asoundlib.h
by Fausto Carvalho Marques SIlva 11 Jul '07

11 Jul '07

In salsa library(this library really saved my life, from am alsa-lib of 600K to 45K!!!), developed by Takashi Iwai, the creation of asoundlib.h is dynamic and based on the configure options ( --disable-mixer will remove mixer.h from asoundlib.h). Can alsa-lib do the same??I think it is a good "cleanup" way of doing client header files. Example from configure.ac from salsa-0.0.6: " echo "Creating asoundlib.h..." cp "$srcdir"/src/asoundlib-head.h src/asoundlib.h test "$mixer" = "yes" && echo "#include \"mixer.h\"" >> src/asoundlib.h test "$rawmidi" = "yes" && echo "#include \"rawmidi.h\"" >> src/asoundlib.h test "$hwdep" = "yes" && echo "#include \"hwdep.h\"" >> src/asoundlib.h test "$timer" = "yes" && echo "#include \"timer.h\"" >> src/asoundlib.h test "$sndconf" = "yes" && echo "#include \"conf.h\"" >> src/asoundlib.h test "$sndseq" = "yes" && echo "#include \"seq_event.h\"" >> src/asoundlib.h test "$sndseq" = "yes" && echo "#include \"seq.h\"" >> src/asoundlib.h test "$sndseq" = "yes" && echo "#include \"seqmid.h\"" >> src/asoundlib.h cat "$srcdir"/src/asoundlib-tail.h >> src/asoundlib.h " Fausto Carvalho Marques Silva

We thought about implementing this in the kernel driver, but after some investigation, we found that we are serializing the driver so much by providing three interfaces (audio, sco and Nav). say pcmC0D0p/c, pcmC0D1p/c and pcmC0D2p/c. Consider the case of two apps audio and sco. We have two interfaces for this pcmC0D0p/c and pcmC0D1p/c priority is audio < sco so interface priority is pcmC0D0p/c < pcmC0D1p/c. Assume that audio is already opened. When we open sco interface audio interface can be in any state, it i can be in paused state or it is about to close etc. So we will have so many states of application in the kernel driver. we need to maintain all these states of application in the kernel driver. Say tomorrow one more application came in to picture, then this complexity will increase. Locking of states of streams is also required in this case. correct me if I am going wrong > > BTW, any reason to drop Cc to alsa-devel ML?

[alsa-devel] Writing a new plugin for ALSA
by Nobin Mathew 10 Jul '07

10 Jul '07

Hi, I am trying to write a new ALSA plugin, like dmix. My intend is to give priority to streams, i will not do up sample and down sample as we do in the case of dmix. If we do up sample and down sample then I think it will take lot of cpu. In my case I have three streams audio, bluetooth sco and Navigation sound data. priority is audio < sco < Nav audio rate is 44100hz, sco rate is 8000hz when sco is up audio should pause playback and audio should continue when sco is finished. I dont want to do software mixing. Thats why I am trying to write this new plugin. Assume that audio is active first, then sco comes to active state. So what i will do is in the library i will put audio app in sleep(), and re-configure the pcm for sco. Once sco is finished i will re-configure pcm for audio again like wise. so my question is there any api in the alsa-lib to take a copy of pcm structures, so when audio comes back gain i can use these saved pcm conf to that. Is there any api in the alsa-lib to reset the pcm structure to initialized state, means state just after open. Thanks Nobin Mathew

[alsa-devel] Unable to find an usable access for 'default'
by Timur Tabi 10 Jul '07

10 Jul '07

I'm developing a new ASOC driver, and I get this error message: ALSA lib pcm_plug.c:729:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'default' Can someone tell me what this means? FYI, I'm in the early stages of testing my driver, and before I started I knew nothing about ALSA. This is on an embedded system, so I don't know if my ALSA installation is correct. Am I missing some kind of configuration file? -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] Intel hda ICH7 not worked anymore after using wine
by Xavi de Blas 09 Jul '07

09 Jul '07

Hello, I installed Wine on my Ubuntu Feisty on IBM-lenovo X60s, and after reboot, sound never worked again. I tried to activate and to hide modem on the bios. I tried to stop machine, take off battery, wait 10s, put battery again, and boot without the power cable connected... and i tried lots of things from ubuntuforums. I reinstalled feisty and sound doesn't work. I used alsa-info.sh script, here is the result: http://pastebin.ca/610317 Should the new kernel 2.6.22 help me? http://kernelnewbies.org/Linux_2_6_22#head-0d133cda430e5d18f1c72dd3cfaa6a92… Thanks

[alsa-devel] Question about write asoc driver
by Roy Huang 09 Jul '07

09 Jul '07

Hi guys, I am write a codec driver under asoc frame work for ad1980 by study the sample driver wm9712.c. I find there are some control item likes "out3 switch" to control 16h:15. There are also some widget item likes "out 3 PGA" to control 24:5. How can I determine a register bit should be a control item or widget item? Thanks ahead. -Roy

[alsa-devel] M-Audio Audiophile USB, native little endian (S16_LE) ?
by Hakan Lennestal 09 Jul '07

09 Jul '07

Hi all ! I don't know if this is already known (?), but the M-Audio Audiophile USB seem to be possible to run in native S16_LE mode if initialized with device_setup=0x01 (possibly with 0x11 also, have not tested that). This is at least the case with my rather new box (bought a couple of weeks ago). Patch for usb/usbaudio.c (alsa-driver-1.0.14): static int is_big_endian_format(struct snd_usb_audio *chip, struct audioformat *fp) { switch (chip->usb_id) { case USB_ID(0x0763, 0x2001): /* M-Audio Quattro: captured data only */ if (fp->endpoint & USB_DIR_IN) return 1; break; case USB_ID(0x0763, 0x2003): /* M-Audio Audiophile USB */ + // Is small endian if setup with 0x01 ! + if (device_setup[chip->index] != 0x01) return 1; break; } return 0; } /Håkan

[alsa-devel] [HDA Intel/STAC92xx] mic not working (retasking?)...
by Daniel J Blueman 09 Jul '07

09 Jul '07

With both 2.6.20 and 2.6.22 kernels on Ubuntu 7.04 on my Sony Vaio SZ240, I'm unable to get my mic connector working at any cost. Well, almost...reading from /dev/dsp, I do see a minute change from 127 for 126 or 128 if I tap my external mic. This would imply the jack-retasking feature of this darn STAC chipset, right? How can I change the jack retasking with the Intel HDA drivers or get further insight into this problem?

[alsa-devel] hda-intel on macbook: unknown model for ACL882
by Steffen Schulz 07 Jul '07

07 Jul '07

Hi all, Since I didn't get much feedback on alsa-users, I figured I'd place a pointer here, too. The revision 3 macbook pro(santa-rosa) ships with a ALC882. Loading hda_intel with auto-detection results in very VERY quiet sound out of the headphones if 'front' is set to 100%, mic input seems to work too, but also very quiet. Providing an option 'model=w2jc' to modprobe however results in working(loud) front and mic. But this model does not seem to provide headphones output, so they don't work. This sounds to me like it may be easy to fix, so I hope you find this information useful. Would be great to have the sound working.
