+This suite automates the validation of audio playback capabilities on Qualcomm Linux-based platforms. It supports PipeWire, PulseAudio, and direct ALSA backends with robust evidence-based PASS/FAIL logic, asset management, and diagnostic logging.

-- Supports **PipeWire** and **PulseAudio** backends
+- Supports **PipeWire**, **PulseAudio**, and direct **ALSA** backends
 - **10-clip test coverage**: Comprehensive validation across diverse audio formats (sample rates: 8KHz-48KHz, bit depths: 8b-32b, channels: 1ch-8ch)
 - **Flexible clip selection**: 
   - Use generic config names (playback_config1-playback_config10) for easy selection

-- PipeWire: `pw-play`, `wpctl`
-- PulseAudio: `paplay`, `pactl`
-- Common tools: `pgrep`, `timeout`, `grep`, `wget`, `tar`
-- Daemon: `pipewire` or `pulseaudio` must be running
+- PipeWire: `pw-play`, `wpctl`
+- PulseAudio: `paplay`, `pactl`
+- ALSA: `aplay`, `amixer`, `alsaucm` when UCM is available
+- Common tools: `pgrep`, `timeout`, `grep`, `wget`, `tar`
+- Daemon: `pipewire` or `pulseaudio` must be running
+
+## Backend and Route Selection
+
+When no backend is requested, the suite uses automatic selection. A physical PipeWire audio sink uses `pw-play`, and a physical PulseAudio sink uses `paplay`. Dummy, null, monitor, and loopback PipeWire sinks are not accepted as speaker routes.
+
+If automatic selection finds no physical managed speaker sink, the suite probes direct ALSA playback. It selects an ALSA card and PCM from the available device inventory, applies only mixer controls exposed by that card, and runs `aplay -D <device>`. This supports the Shikra primary-MI2S, secondary-TDM, and codec-direct route capabilities without selecting a form factor or assuming card `0`.
+
+An explicit backend request is never replaced:
+
+- `--backend pipewire` or `AUDIO_BACKEND=pipewire` runs `pw-play` only and skips if PipeWire has no physical speaker sink.
+- `--backend pulseaudio` or `AUDIO_BACKEND=pulseaudio` runs `paplay` only and skips if no matching sink is available.
+- `--backend alsa` or `AUDIO_BACKEND=alsa` runs `aplay` with the discovered ALSA route.
+
+## Audio Remoteproc Preflight
+
+Before backend discovery, the suite enumerates runtime remoteprocs and checks the configured firmware and topology under `/lib/firmware` or `/usr/lib/firmware`. It recognizes audio DSP identities and the Shikra modem-hosted audio path. A remoteproc named `modem` is ignored on non-Shikra targets because it is not their audio preflight dependency.
+
+If the matching remoteproc is `running`, the suite records its name and firmware evidence. If it is `offline`, the suite starts it only after confirming the corresponding firmware is provisioned. Generic audio DSP paths also require adjacent topology evidence. Shikra's modem-hosted path does not require an adjacent topology file because its public image packages `qdsp6sw` modem firmware and `lpaicp` audio firmware separately. The suite never stops a remoteproc. Platforms with no applicable audio remoteproc continue normally. Provisioning or start issues produce a clean skip with the reason.
