Hello, I have the same issue with my HP Envy 15. The sound card in question is an HP Wireless Audio card that only works with HP-branded wireless speakers, so playing to the card produces no output whatsoever, but does hang whatever process tries to access it. I doubt that many people ever use this feature, so unless someone invests the time to get it working I'd like a way to just ignore it completely. I've blacklisted the snd-usb-audio module for now, but I have a USB sound card and a USB MIDI controller that I'd like to be able to use.

[alsa-devel] Denon DN-X 1600 Support
by Florian Beginn 11 Dec '12

11 Dec '12

Hello, i just made my first steps fiddling with the alsa-driver and got my DN-X 1600 working. It's a dj-mixer connected via usb, offering 8 channel input/output and midi. Samplerate can be set to either 44.1, 48 or 96khz. It seems to not answer properly on samplerate requests from snd_usb_ctl_msg() so i hardcoded it to 96khz. Regrettably, this is a pretty ugly workaround and somehow broke midi capability, although audio is running fine. I'd be happy if one of you could help me work out how to do this right/better. Find attached the patches and all information i could gather. P.S. I'm not used to git (well, any VCS) and hope the diff format is ok for you. --- a/sound/usb/clock.c 2012-01-25 08:56:49.000000000 +0100 +++ b/sound/usb/clock.c 2012-12-11 17:33:47.685196544 +0100 @@ -255,6 +255,14 @@ int err, crate; int clock = snd_usb_clock_find_source(chip, fmt->clock); + /* + * Denon DN-X 1600 won't respond when asked for samplerate. + * Currently hardcoded to only work with 96khz + */ + + if (chip->usb_id == USB_ID(0x154e, 0x500e) && rate == 96000) + return 0; + if (clock < 0) return clock; --- a/sound/usb/format.c 2012-12-07 17:11:00.000000000 +0100 +++ b/sound/usb/format.c 2012-12-11 17:42:14.069181583 +0100 @@ -281,6 +281,21 @@ int nr_triplets, data_size, ret = 0; int clock = snd_usb_clock_find_source(chip, fp->clock); + /* + * Denon DN-X 1600 won't respond when asked for samplerate. + * Currently hardcoded to only work with 96khz + */ + if (chip->usb_id == USB_ID(0x154e, 0x500e)) + { + fp->nr_rates = 1; + fp->rate_min = 96000; + fp->rate_max = 96000; + fp->rates = SNDRV_PCM_RATE_96000; + fp->rate_table = kmalloc(sizeof(int), GFP_KERNEL); + fp->rate_table[0] = 96000; + return 0; + } + if (clock < 0) { snd_printk(KERN_ERR "%s(): unable to find clock source (clock %d)\n", __func__, clock); --- a/sound/usb/pcm.c 2012-01-25 08:56:49.000000000 +0100 +++ b/sound/usb/pcm.c 2012-12-11 17:57:11.579301294 +0100 @@ -198,6 +198,13 @@ if (!(fmt->attributes & UAC_EP_CS_ATTR_PITCH_CONTROL)) return 0; + /* + * Denon DN-X 1600 doesn't properly handle this -> bail out, too + */ + + if (chip->usb_id == USB_ID(0x154e, 0x500e)) + return 0; + switch (altsd->bInterfaceProtocol) { case UAC_VERSION_1: default: cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.25. lsusb (...)

[alsa-devel] [PATCH 2/2] Rename internal xonar_u1_* names to just xonar_u_*

[alsa-devel] how this will happen about hw_ptr_buffer_jiffies?
by l9jj 11 Dec '12

11 Dec '12

recently,i am tracing the process into the snd_pcm_update_hw_ptr0() and find the statement. i do not understand when the if (hdelta > runtime->hw_ptr_buffer_jiffies/2) (1)will happen? (2)and the reason? (3)the other question is if the dma interrupt will can enter the snd_pcm_update_hw_ptr0() every time when it ocurrs? thanks for any suggestion. Best Regards L9jj =====================code start==============================> if (in_interrupt) { /* we know that one period was processed */ /* delta = "expected next hw_ptr" for in_interrupt != 0 */ delta = runtime->hw_ptr_interrupt + runtime->period_size; if (delta > new_hw_ptr) { /* check for double acknowledged interrupts */ hdelta = jiffies - runtime->hw_ptr_jiffies; if (hdelta > runtime->hw_ptr_buffer_jiffies/2) { hw_base += runtime->buffer_size; if (hw_base >= runtime->boundary) hw_base = 0; new_hw_ptr = hw_base + pos; goto __delta; } } <=====================code end============================ -- ------------------------------------ l9jj Regards
