2009-04-07sound: usb-audio: allow period sizes less than 1 msClemens Ladisch1-20/+86
To enable periods shorter than 1 ms, we have to make sure that short periods are only available for alternate settings that have a small enough data packet interval. Furthermore, the code that aligns URBs to USB frames is now superfluous. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-04-07sound: usb-audio: save data packet interval in audioformat structureClemens Ladisch1-6/+21
The data packet interval needs to be available in the audioformat structure, together with the other audio format parameters, so that it can be used to influence ALSA hardware parameters. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-04-07sound: usb-audio: remove check_hw_params_convention()Clemens Ladisch1-116/+19
This removes the check_hw_params_convention() function because 1) it is not necessary, as the hw_rule_* functions also work correctly (i.e., as no-ops) when the device supports all combinations of the audio format parameters; and 2) it would become too complex when adding a fourth altsetting-dependent hardware parameter, as this would require another three loops to check dependecies with rate/channels/format.

2009-04-07sound: usb-audio: show sample format width in proc fileClemens Ladisch1-1/+2
When listing the device's sample formats in the stream? proc file, the sample format number itself is rather obscure, so we better show the format width, too. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-03-18ALSA: snd-usb-caiaq: drop bogus iso packetsDaniel Mack3-1/+9
Drop inbound packets that are smaller than expected. This has been observed at the very beginning of the streaming transaction. And when the hardware is in panic mode (which can only very rarely happen in case of massive EMI chaos), mute the input channels.

2009-03-02sound: usb-audio: fix queue length check for high speed devicesClemens Ladisch1-3/+2
When checking for the maximum queue length, we have to take into account that MAX_QUEUE is measured in milliseconds (i.e., frames) while the unit of urb_packs is whatever data packet interval the device uses (possibly less than one frame when using high speed devices).

2009-03-02sound: usb-audio: fix rules check for 32-channel devicesClemens Ladisch1-2/+2
When storing the channel numbers used by a format, and if the device happens to support 32 channels, the code would try to store 1<<32 in a 32-bit value. Since no valid format can have zero channels, we can use 1<<(channels-1) instead of 1<<channels so that all the channel numbers that we test for fit into 32 bits.

2009-02-17ALSA: usb-audio - Workaround for misdetected sample rate with CM6207Joris van Rantwijk1-1/+2
The CM6207 incorrectly advertises its 96 kHz playback setting as 48 kHz in its USB device descriptor. This patch extends an existing workaround in usbaudio.c to also cover the CM6207.

2009-02-16sound: usb-audio: fix uninitialized variable with M-Audio MIDI interfacesClemens Ladisch1-0/+1
Fix the snd_usbmidi_create_endpoints_midiman() function, which forgot to set the out_interval member of the endpoint info structure for Midiman/ M-Audio devices. Since kernel 2.6.24, any non-zero value makes the driver use interrupt transfers instead of bulk transfers. With EHCI controllers, these random interval values result in unbearably large latencies for output MIDI transfers.

2009-02-06sound: usb-audio: handle wMaxPacketSize for FIXED_ENDPOINT devicesClemens Ladisch1-0/+1
For audio devices that do not have proper audio descriptors (e.g., Edirol UA-20), we use hardcoded parameters from our quirks list. However, we must still read the maximum packet size from the standard endpoint descriptor; otherwise, we might use packets that are too big and therefore rejected by the USB core.

2009-01-26sound: usb-audio: make URB sizes more equalClemens Ladisch1-24/+5

2009-01-26sound: usb-audio: limit playback queue lengthClemens Ladisch1-1/+8
Once our URBs contain enough packets, queueing more URBs does not give us any additional underrun protection (as we use double-buffering) but just increases latency unnecessarily.

This patch extends 42a6e66f1e40a930d093c33ba0bb9d8d8e4555ed by using usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk, and usb_endpoint_xfer_int in the negated case as well. This patch also rewrites some calls to usb_endpoint_dir_in as negated calls to !usb_endpoint_dir_out, and vice versa, to better correspond to the intent of the original code.
