[alsa-devel] 48kHz SPDIF out on X-Fi?
by Lucas Marshall 04 Dec '09

04 Dec '09

Is it possible to get the optical SPDIF on an X-Fi Titanium to output at 48kHz instead of 96kHz? I've tried doing a rate convert in .asoundrc, adding a rate to the hw plug in there, etc. but no matter what it's still spewing 96kHz according to my test receiver. We would like to do a SPDIF-to-AES conversion, and our video/audio router won't take anything but 48kHz. :( Thanks in advance for any suggestions! -- Lucas Marshall Systems Administrator // Media Systems Lucasfilm 415-746-2861

Re: [alsa-devel] [Alsa-user] m-audio delta 1010 inputs crackle at 96 kHz sample rate with all newer kernels

The first kernel that broke was a newer 64 bit one. I switched to 32 bit Linux a few months later to try it out because I had other problems. However, this particular problem persists.

[alsa-devel] snd-fm801: autodetect SF64-PCR (tuner-only) card
by Ondrej Zary 03 Dec '09

03 Dec '09

When primary AC97 is not found, don't fail with tons of AC97 errors. Assume that the card is SF64-PCR (tuner-only). This makes the SF64-PCR radio card work "out of the box". Also fixes a bug that can cause an oops here: if (tea575x_tuner > 0 && (tea575x_tuner & 0x000f) < 4) { when tea575x_tuner == 16, it passes this check and causes problems a couple lines below: chip->tea.ops = &snd_fm801_tea_ops[(tea575x_tuner & 0x000f) - 1]; Tested with SF64-PCR, but I don't have any of those sound or sound+radio cards to test if I didn't break anything.

Hello, I'm having additional issues with this sound card. There is no CD audio listed in alsa at all, when playing a CD, there's no sound. I thought there was a separate channel for CD audio? Thanks, Shawn.

[alsa-devel] io-plugin does not call start callback function
by Stefan Schoenleitner 03 Dec '09

03 Dec '09

Hi, I'm writing an io plugin that should transfer all PCM samples to a UNIX socket. For this reason in my plugin I open the socket and then fill the plugin struct like this: socketdump->io.mmap_rw = 0; socketdump->io.poll_fd = socketdump->sock_fd; socketdump->io.poll_events = POLLOUT; Thus for my understanding (the alsa doc is really bad), every time the socket file descriptor is available for writing the alsa plugin would generally speaking issue a data transfer. However, when playing audio over that plugin for some reason the start callback function is never called. Instead I get output like this: socketdump_hw_constraint:417 26944 _snd_pcm_socketdump_open:585 26944 SND_PCM_PLUGIN_DEFINE_FUNC(): done, err=0 Playing WAVE 'test_8khz_16LE_mono.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono snd_pcm_socketdump_prepare:309 26944 Preparing with io->period_size=164 io->buffer_size=3936 snd_pcm_socketdump_pointer:229 26944 hw_ptr: 0 () snd_pcm_socketdump_write:268 26944 snd_pcm_socketdump_write(): areas->step=16 areas->first=0 areas->addr=0x22f1f60 offset=0, size=164 io->nonblock=0 ...... Do you have any idea why the start callback function is not called at all ? cheers, stefan

[alsa-devel] [PATCH] ASoC: DaVinci: Update suspend/resume support for McASP driver
by Chaithrika U S 03 Dec '09

Add clock enable and disable calls to resume and suspend respectively. Also add a member to the audio device data structure which tracks the clock status. Tested on DA850/OMAP-L138 EVM. For the purpose of testing, the patches[1] which add suspend-to-RAM support to DA850/OMAP-L138 SoC were applied.

[alsa-devel] io plugin: playback and capture over a socket
by Stefan Schoenleitner 03 Dec '09

03 Dec '09

Hi, I'm having difficulties writing a simple alsa plugin that plays and captures from a socket. The background is that there should be a "server" application that processes PCM data. In order to "connect" ALSA to that application I would like to use a socket. I looked at the bluez bluetooth audio plugin which seems to do a similar task. Basically the idea is that the alsa plugin transfer callback function just sends and receives PCM samples in periods to/from the socket (depending on whether the plugin is used for playback or capture). To control the timing and to increment the hw_ptr a separate thread in the alsa plugin is used. Basically for each period the thread will increment the hw_ptr and signal to the alsa plugin that the next period can be written. This signaling is done by using a pipe. As the plugin code is poll-based I guess it needs to poll both the socket and the pipe (which is used to communicate with the "timing" thread). For this reason the alsa plugin would only write to the socket if the socket is ready for writing _and_ the time for writing the next period has come (which will be signaled by a write to the pipe by the timing thread). Would such a implementation work so far ? At the moment I'm having some real difficulties as for some reason the start callback function that would start the thread is not called at all. My code is pretty much the same as in the bluez bluetooth audio plugin. cheers, stefan
